ToME: the Tales of Maj'Eyal

Blade Halo | Passive
Shape the earth into a set of 4 blades of solid stone that hover behind you. Each time you use a talent or make an attack, up to (1 + Con/10) blades will strike a random target within range 7 for 100% damage.
You may also activate this talent to fire a blade in a piercing line for 150% damage, which consumes the blade.
You regenerate one blade every 5 turns.
The base power, Accuracy, Armour penetration, and critical strike chance of your blades increases with your Spellpower, and the maximum number of blades you can attack with at a time increases with your Constitution.
Stoneblades count as melee attacks for the purpose of on-hit effects.

Stonereaver | 6 Cooldown | 24 Mana
Grasp one of your stoneblades and form it into a mighty stone axe, sweeping it in a radius 2-5 semicircle that deals 150-280% damage to all within.
This attack strikes with such force and speed that it never misses and leaves targets staggered, causing weapon attacks against them to gain 10-25% increased critical strike chance and critical strike power for 3 turns.
Costs 1 stoneblade to use.

Mountain Hammer | Sustain | 20 Cooldown | 50 Mana
Form a pair of stoneblades into a massive stone hammer that mercilessly crushes the target, striking them for 40-100% damage each turn with a 5-15% chance to daze.
The hammer increases in power and cost each turn it is sustained, increasing the mana drain, damage dealt and chance to inflict a status effect by 50%, to a maximum of 120-300% damage and 15-45% chance to daze.
This sustain takes no time to deactivate.
Costs 2 stoneblades to use

Obsidian Edge | Passive
Your stone weapons are lined with superheated, razor sharp obsidian, inflicting terrible wounds on those they strike.
Critical strikes will randomly cause a searing wound or a deep wound, lasting 5 turns.
Deep Wound: Bleeds targets for 30 physical damage each turn and reducing their healing received by 15-45%.
Searing Wound: Burns targets for 30 fire damage each turn and reduces armor by 5-25.
If the target is already affected by both, this refreshes the duration.
The damage dealt will increase with your Spellpower.

Desert

Sirocco | 5 Cooldown | 20 Mana
A desert wind appears in radius 2-4, creating sand tiles on the target area. After 4-2 turns, the target area erupts into a searing cyclone, dealing 320 fire damage to those within and pulling them towards the center.

Dessicate | 12 Cooldown | 30 Mana
Evaporates the moisture from the target’s body over 3 turns, leaving them a withered husk. This inflicts 90 fire damage each turn, while causing beneficial physical effects to reduce in duration twice as fast. At talent level 2 magical effects are reduced, and at talent level 4 mental effects are reduced.
If the target is standing on sand, this effect will not decrease in duration.

Scorching Sands | Passive
Your sand burns with intense heat, inflicting 40 fire damage each turn to those within and leaving them weakened and drained, reducing powers and saves by 5-25.

Entomb | 18 Cooldown
All sand tiles in radius 1-3 erupt upwards, forming pillars of burning sand for 3-5 turns. Empty tiles will become summoned walls, and enemies will take 280 fire damage and be encased in sand for the duration, entirely removing them from combat until the pillar crumbles or is destroyed.

Sand (Generic)

Erosion | Passive
Even the smallest grains of earth bend to your will. Each time you summon a wall, you also summon sand to cover tiles in radius 1-2, lasting 3-5 turns. Sand makes the ground difficult to walk on, reducing movement speed by 30-50% and reducing pin and knockback resistance by 50%.
You are immune to the negative effects of sand.

Dunestalker | 10 Cooldown | 12 Mana
You dissipate into a cloud of sand, quickly reforming at a tile in range 5-10 with a margin of error of 3-1 tiles.
If you are standing on a sand tile, this takes no time to use.
If the target tile is covered in sand, this has perfect accuracy.

Sandstorm | 20 Cooldown
A radius 4 storm of sand rages around you for 5-10 turns. Tiles within the storm have a 25% chance to be covered in sand, enemies within the storm will be blinded and have their accuracy reduced by 10-50, and attacks against you originating from outside the storm deal 10-40% reduced damage.

Colossus | 25 Cooldown | 50 Mana
You merge together all sand tiles in radius 2-4, forming it into a titanic sand golem for 4-7 turns. Each tile consumed increases all attributes of the colossus by 1.
If a radius 2 area of sand is consumed, the duration of the colossus is doubled, and it will gain the ability to breath blinding sand.
If a radius 3 area of sand is consumed, the colossus will also gain increased physical damage and penetration, and learn the ability to pull targets towards it.
