The Firmamancer: Celestial Weather Mage

[astralInferno]

Hello, and welcome to yet another class!

The Firmamancer, available here, is a celestial mage. They generate negative energy by moving and casting, and their negative spells are highly damaging. Their positive spells are easy to cast but less powerful. Ideally, this grants their playstyle a feel of building up to a crescendo.
They have access to the following existing class categories:
Celestial/Sunlight (Unlocked, one of their primary energy generators)

As for Generics, they have Light and Hymns unlocked. Hymns are modified to grant +Cold damage. (Compatible with Midnight's changes - but, now I think of it, won't do anything if you turn the midnight changes off, or might error.) They also have Chants and Divination as locked categories.

This addon also alters Celestial/Sunlight, giving it a new damage spell and a healing sustain, and grants Celestial/Rainfall and the new Celestial/Blaze to Anorithils. Blaze receives the two spells removed from Sunlight.

But the fun things are the new trees, and the changes to existing trees!

Celestial/Sunlight (Modified core tree)

Searing Light
(As core, slight damage boost)

Sun Flare
(As core)

Dazzling Flare
You can release a bolt of light with a range of %d, striking the first foe it encounters for %0.2f light damage.

Stream of Life
Your divine energy heals you even as it scours your foes from the world. All light and fire damage you deal also heals you for %d%% of the damage done.
(It's a low %. Maxes at 10% with mastery 1.0, so likely 13% or so?)

Control the rain through positive energy.

Downpour (Negative Pos cost)
Cause it to rain furiously in a radius 2 ball within 6, dealing low cold damage.
The damage will increase with your Spellpower.

Known Bugs
-

Planned Features/Changes
-

1.0.1 (Hoboy I hope I remember everything.)
Dynamo and Genesis pretty much halved negative rates. No longer grant movement/spell speed.
Indignation and Laughing Gust now cost 90% of max negative.
Words of the Sun now grants healing factor. Words of the Wind now grants spell cooldown reduction. (Words of the Wind now has a blue particle.)
Forecast tooltips massively enhanced: They now list all benefits they grant from any talents in their tree.
Revelations now grants a short(er) radius Track effect instead of yet more retaliatory damage.
Uneasy Skies negative regen effect is gone. It now has the 'when hit for X% damage, gain a turn' passive from Splintered Gale.
Splintered Gale now has the attack speed from Genesis.
Long Summers now has healing factor on it.
Aura of the Dawn no longer does.
Minor cost refactoring for a few things.

1.0.2 and 1.0.3 cause I forgot to change base stuff
New tree: Celestial/Blaze. This tree is only given to Anoritihils. Firebeam and Sunflare have been moved to this tree. (The Midnight changes to Sunflare are also included in this addon - it causes burning as well as its light damage.
Changes to: Celestial/Sunlight. Sunflare and Firebeam are now Blaze talents. Two new sunlight talents have been added. Searing Light has also been buffed.
Downpour was also buffed a little, as was Floodgate
Drench is now Instant.
Open the Heavens... hasn't changed. I couldn't easily make the neg 'cost' scale.
New talents: Dazzling Flare, Stream of Life, Astral Inferno, Divine Fire.

1.0.4 and then 1.0.5 cause I'd not done something that I'd put in a tooltip.
Damaging Rainfall talents have a chance to cause wet - 25% for downpour and open the heavens, 50% for floodgate. Open the Heavens grants scaling neg.
The Storm tree has been renamed the Tornado tree. This does not alter its code name, and I THINK it's compatible with saves?
new positive generator tree: Celestial/Firmament, which provides darkness damage and CC.
new negative heavy tree: Celestial/Drought, which debuffs foes. Its generator talent grants negative energy on waiting a turn.
three new high level trees.
Celestial/Blizzard: Cold+physical, featuring a massive MS slow and random knockback.
Celestial/Thunderstorm: All of the wet synergy. Also, musical storm power??
Celestial/Meteorology: Meteors. Yup.
locked spell trees removed. Sorry.

1.0.6
QOL: At talent level 5, The Heavens Fall has a radius of 1 and a range of 8. This means things in the centre of the target area cannot be missed, I think.
Hunger now goes on cooldown. Oops.
Scarlet Wind no longer makes a particle effect every time it activates; that was irritating clutter.

[Einander]

The class concept is very interesting. Taking the whole cycling concept of the Celestial classes and adding movement to that is cool. And you made the --off huge lightning signature spell Indignation, which I can only applaud. I, who stand in the full light of the heavens, command thee...

Only actual bug I've noted so far: only Words of the Sun has a Sustain cost associated with it, Words of the Wind and Storm are free.

The details kind of need some serious tweaking, though.

- Indignation and Laughing Gust are already fantastic, and leveling the two of them would be enough of a perk by themselves; tying them to such strong passives just ensures that they max out nearly instantly, making them hilarious overkill while simultaneously ensuring that they're very, very easy to cast.
- The fact that you can activate Genesis by casting spells at empty space means that you can walk into every fight with maxed-out Negative. (This is especially silly if you're one of the classes whose insta-buff racial is a Spell, like Ogres.) And most Negative spells get refunded for most of their cost, especially Star Fury, so when you get to full Negative you basically stay there. This should probably be limited to one or more of a) spells you cast on an enemy, b) spells that generate Positive energy, or c) somehow limited by enemy rank or level (scales up against stronger ones?), on top of almost certainly needing a number nerf.
- Similarly, Dynamo needs the nerf-hammer on the Negative generation. Costs aren't that high, even for the two big spells.
- Hymns, Forecast, and Revelations all have stacking self-damage (and Revelations does a LOT of it). You should probably diversify that a bit.
- Out of Forecast, Storm is a lot stronger than the other two; HP regen is more a convenience than anything and the +armor/def/hardness doesn't matter until you invest some points in armor (and that requires strength and buying the tree and you've got the Light tree to focus on instead). The fact that you can turn it off to reduce spell cooldowns just encourages you to leave it on all the time.
- Why so many spells that generate Positive when there's only two spells to spend Positive on (and they're very cheap)? Plus, "Rain = Light Energy" is kind of weird. Just kick that whole tree over to costing Positive; at the current costs, you can cast any Rainfall spell in two casts of any other Light or Sunlight spell.
- Why is there even a Sustain that exists to give you a bunch of +Negative when you have two other +Negative sustains and a spell that explicitly exists to give you a ton of it (while also doing other stuff)? Like, at that point, said Sustain is not even unbalanced, because the balance of that point is already a null issue.
- Splintering Gale should not be on a class with the Light tree. Like, full stop, don't, that's way too close to making you actually invincible. The fact that the class also gets Aura of the Dawn (I see what you did there) for a super version of the Aegis tree shield buff Sustain (with no actual cost) to improve said healing/shielding then crosses said "actually invincible" line. And those talents also boost damage/penetration for some reason ahhhhhhhhhhhhhhhh why do you keep taking two good abilities and mashing them together

You've basically got a class that has interesting tactical decisions that it never gets to actually use, because you've ensured that it never ever has any resource management at all. It also can't die once it hits level 22, which removes the other dimension of actual game-playing. At that point, what do you have left, other than collecting loot? You're just going through the motions of a game you've already won.

You've got a good concept, just based off how the class works at level 1: two incredibly expensive spells it can fuel by movement or by spellcasting, lower-powered spells it can always cast, some defense. Extrapolate that out so that this is always true and you have a fun class.

So say that Indignation and Laughing Gust always cost 90% of your max Negative. Now you've got an interesting central tension of the class, because you want a higher max Negative for the other abilities but a lower max Negative for the two big nukes. Add some interesting Sustains that give you lower max Negative, some that give you higher; Scarlet Wind, Uneasy Skies and Splintered Gale will be the minimized Negative ones, while Blinding Presence, Long Summers and Aura of the Dawn will be the maximized Negative ones.

Now you've got a big fight. You have two options for the two philosophies.

The first is to go in with your Negative minimized. You take a step, hit max Negative, Starfall, step, Indignation, step, Laughing Gust. Scarlet Wind makes you faster and stronger every time you do damage or move (and the bonus goes away once you do anything else), Uneasy Skies reduces your cooldowns every time you take a big hit, Splintered Gale reduces your cooldowns every time you hit low Negative, and you can deactivate Words of Storms for a quick cooldown boost; you become a living tornado, seeking to blitz down every single enemy in the room before you have to stop and heal (or shield). Death-Dealing Journey, Hurricane's Opened Eye and other spells let you move around and move enemies while you're killing them, in keeping with the theme.

The second is to go in with your Negative maximized. Blinding Presence, Long Summers, and Aura of the Dawn now all provide bonuses while your Negative is high, so you focus on your Positive spells, relying on your fortress-like defenses to keep you going. Indignation and Laughing Gust become panic buttons, while other Negative spells become more about other effects (or for use while your other skills are cooling down). Rainfall costs Positive now, because it's more of an alternative big tree if you want to reap the benefits of a high Negative.

Or you can just activate all of the Sustains, oscillating between the extremes and reaping the benefits accordingly, or start one way and work the other. Any way you go, you're making interesting decisions! That's what games are all about.

[sixthcircle]

super cool concept and i can't wait for balance tweaks. keep up the good work

[Effigy]

Yeah, it's a nice concept. Bonus points for working in offensive rainbows.

[astralInferno]

First off, thanks for the feedback, and the compliments where they are. Sorry balance is coming out slowly, I like to play a game through to dreadfell before I make sweeping changes (although at least some of your points are very, very valid and may be changed before I do that run.)

To address specific points.

Words of the Wind/Storm bug will be addressed. I almost noticed that in function testing, dang. X_x

Indignation and Laughing Gust being auto maxed. I... honestly don't know if I see that as a downside. You need the negative generation for the class to function, and you always want to max your primary damage spells. You may be right in saying that the extra benefits on Dynamo and Genesis are excessive; I'll consider nerfing or just removing them.
Both Genesis and Dynamo will be having the negative regen nerfed. Probably straight up halved. Genesis will probably get the same limiter Dynamo has - it only triggers when casting spells with an enemy in sight. If I can finagle it, I might have it only apply to spells that take time to cast; I think that's doable. I'm also considering having it not proc on spells with a negative cost.

The damage-on-hit stacking was pointed out on the IRC pretty much immediately. I somehow forgot hymns/chants/forecast when I was trying to think of something cool I could put on top of Revelations. I'll see if I can swap it out for something else. Maybe it can get one of the passives that Genesis and Dynamo had, but it should probably be another active component to go with the shield.

Problem with Forecast is that chants and hymns cover most of the game's stats between them.
...that said. Maybe I can put a healing factor on Sun, and then something about speed on Wind. Then you have tank/speed/power for your choices.
The deactivate benefits are literally healing light/barrier/half of Totality. I specifically made them strong because I never have the patience to micro them with hymns and chants, but these are strong enough that I might remember.

You'll notice that Anorithil and Sun Paladin also have a lot more positive generation than they will ever need. The idea is that you can always, always cast your positive spells to generate negative energy. Honestly, they could have no resource costs at all and the gameplay would be the same.
Similarly, if I make Rainfall cost positive, it no longer serves the purpose of building up negative. If you have to build up positive so you can cast rain so you can get to lightning... I'll grant you, that's a pretty cool idea, but no non-boss is ever gonna see it, and it means you absolutely /must/ spec into sunlight, rainfall, and one of the two damage trees. I tried to design it so you could go pure sun/wind or pure rain/lighting or sun/lightning or rain/wind; the two trees with positive 'costs' serve the same purpose, as do the two with negative costs.

Long Summers is... a bit of an oddity? It looks strong, and it is in combination with Uneasy Skies, but on its own it has very little effect. It means you can build up for longer if you like, for a bigger payoff, but since you have no reliable way to get straight up negative regen (Midnight Hymns 4 can sort of do it, but means you have to account for moonlight bolts everywhere) it doesn't actually do much. Plus, honestly, I really really like it as a design; letting you do the core pattern of the class but more.

I'm not sure Splintered Gale has as much synergy with Light as you think? The weakness of Light spells taking a turn is a thing, yeah, but it's not infallible. Reavers can largely bypass it.

For both Splintered Gale and Aura of the Dawn, I started with the damage amp and then tried to find an interesting bonus to stick onto it (All the others have one; tempest has dazing, uttercold has iceblock pen, wildfire has self-damage resistance, pure aether has... does pure aether have anything? Just the Aegis allowance? That's pretty boring. Frostdusk has healing, crystalline focus has saves.). You're probably right that the bonuses are in themselves way too strong. Aura of the Dawn might be okay with a value nerf; maybe I can take the healing factor and put it on Long Summers in place of the boring resists, and then leave it with a nerfed Shielding effect. Splintered Gale's fancy effect can perhaps go onto Uneasy Skies' spot; it has the same DOOM OUTTA NOWHERE fluff that the name implies. I then need an actually minor benefit to give Gale though.

I really like the % costs idea for Indignation/Laughing Gust. I very much will consider grabbing that.

...oh! Clarification; Uneasy Skies grants a passive cooldown reduction effect. That's a very unclear tooltip, sorry.

[astralInferno]

Dynamo and Genesis pretty much halved negative rates. No longer grant movement/spell speed.

Minor cost refactoring for a few things.

Astral Inferno (I have no regrets.)
Celestial/Blaze 3
Your light burns the spirit, causing it to set the foe alight and deal %d%% of the light damage as fire over four turns.
You also passively receive %d%% fire penetration.

Divine Fire
Celestial/Blaze 4
Calls forth a column of fire from the Sun, doing %0.1f fire damage to the target.
Fire dealing %0.1f damage will also be placed in a radius 2 around it for %d turns.
The damage dealt will increase with your Spellpower.
Divine Fire will use up the Sun's Vengeance buff as if it were Sun Ray.

If anyone's using this, especially if they also use any of my other addons, could you please try turning it off and starting a new game, just to see if it works? I got a weird error playtesting another addon.

1.0.4 and then 1.0.5 cause I'd not done something that I'd put in a tooltip.
Damaging Rainfall talents have a chance to cause wet - 25% for downpour and open the heavens, 50% for floodgate.
The Storm tree has been renamed the Tornado tree. This does not alter its code name, and I THINK it's compatible with saves?
new positive generator tree: Celestial/Firmament, which provides darkness damage and CC.
new negative heavy tree: Celestial/Drought, which debuffs foes. Its generator talent grants negative energy on waiting a turn.
three new high level trees.
Celestial/Blizzard: Cold+physical, featuring a massive MS slow and random knockback.
Celestial/Thunderstorm: All of the wet synergy. Also, musical storm power??
Celestial/Meteorology: Meteors. Yup.

this compatible with 1.4.6?

Should be!

I just tried the firmamancer for a few levels on nightmare, and it was rough! I wouldn't say that's due to the balancing of the class, more to my relative inexperience with nightmare, total lack of experience with the class and the quirks of the playstyle that I've yet to get to grips with.

Mostly I just wanted to say that the concept of this addon is great. I love the idea of using negative energy as a buildup mechanism during fights. I love the three base methods of gaining negative energy and the idea that doing nothing in the face of a monster is a valid use of a turn. So I hope this addon gets further development love (as far as it needs any, its too early for me to tell) and some love from the community here.

Thanks! My dark secret is that I play normal/exploration, so I'll need expert input if it needs balancing for high difficulties. I hope you keep enjoying it!
