What is the least appreciated prodigy?

[Coldbringer]

When finally getting a character to survive long enough to choose one of these, it tends to be the hardest decision I have to make in the game.

Recently chose Massive Blow for my Doombringer, and wow this is amazing. Hitting for 1-3k criticals every 10 turns and knocking down walls. Even if they don't hit a wall, the knockback has a high chance of working even against foes with good physical resist and can give me a chance to escape or blast them with ranged attacks while they walk towards me again. Uses zero resources, no weapon requirement, can use while disarmed.

My Ogre Berserker died before he go t to try out "You Shall Be My Weapon" but it looks pretty boss from the description.

Which ones have you tried out and been impressed with, that aren't consensus picks?

[jaumito]

Never Stop Running. Especially good on characters with lots of stamina (high willpower) they don't have other uses for.

[OrionJAnderson]

I tried You Shall Be My Weapon. It sucks. Doing 350% is just not that special at level 42; several of my other attacks were better. If appears that if YSBMW kill the first target, then you get no bowling ball effect. If it doesn't killed the first target, the target probably resists the knockback.

armour of shadows? no idea who would use it. maybe anorithil?
but it requires you to stand in shadows to have an effect, then you cannot use it if you have any source of light.
unless the darkness it creates is magical.

Mystical cunning.
rogue doesn't have a use for magic, so that's something we may never see.
neither archer, marauder, nor skirmisher use magic, so they wont make a use of it either.
also, according to wiki shadow blades don't have poisons either.

through the crowd
i do not know of any summoner that would invest in dexterity, unless it was a gimmick.

lucky day.
someone made a math on it, not that impressive.

Requirements can easily be fudged through equipment, so just because it requires 50 of a "weird" stat doesn't really make it a problem. Now, if it requires spell power.... You might have a problem.

I loved irresistible sun or whatever it's called. Though, it's not exactly unpopular.

[Kuroto]

Mystical Cunning is actually really strong on anyone with access to traps, as the Gravitic Trap is just amazing really. The poison is situationally nice as well when you really need to get resists down, and as Micbran said, you can fudge stat requirements to get basically any prodigy through gear later in the game.

You're right that Lucky Day isn't really that great, but hey, its an always on bonus, so it's not like its bad either, but you can definitely do better.

As far as underrated prodigies that are actually pretty decent, the following stand out to me:

Superpower: I see this one getting more love lately, it can be really strong on the right classes. It's often compared to the lackluster Arcane Might, but Willpower is already a stronger stat than Magic (on the right classes), making it better to stack. Willpower scaling can get just insane with Mindstar Mastery. Most importantly, the mindpower bonus from your Strength not only gives you even more damage, but also helps your statuses to reliably land.

Giant Leap: A 10 range jump and aoe that really shines on classes with lackluster movement options. it being a jump instead of a dash or that sort also saves you in cases of having your escape route blocked off. The major downside though is it's 20 turn CD, making it more situational than many of the other options

Windblade: Debatable about whether this can be called underrated, as it is notably strong, I think a lot of people ignore JUST how strong it is. This thing just shreds everything and has a chance to disarm the few things that live, for free, on a fairly low cooldown. I take it on basically any melee that needs a better aoe option. It's not the best, but it puts a smile on my face every time I get a big one off.

[Crim, The Red Thunder]

Lucky day it should be pointed out, is also known as 'the halfling prodigy' for the way it combines with their duck and dodge racial.

Effectively turns it into 100% evasion for the duration.

[Ubenstein]

I Can Carry The World is a personal favorite of mine, I've used it many times with Archmages to wear heavy armor short staff and shields allowing you to be incredibly resilient and have 0 fatigue. effectively making you a wrecking ball and not a glass cannon. It's sexy.

If you make use of your storage room in the fortress you can easily save every yellow (fixed-art) item you ever find in all your runs, as well as randarts you've found and/or created. I feel I could elaborate on this subject all day but if you are patient it's not very difficult to accumulate a set of gear that boosts your strength to +50 without ever having to invest more than 5 points into strength (getting to 16 initially can be annoying depending on difficulty). My point is that if you only need to have 50 strength temporarily at the time you invest the prodigy point. afterwhich you can take off the gear.

I will point out that you'll have 50 strength at least when naked after investing the prodigy point, so wearing heavy armors /shields won't be an issue when you're in spellcasting gears.
