Cryokinesis

is a mental mutation that allows the player to cool nearby areas with their mind, dealing damage to and decreasing the temperature of those within.

Cryokinesis grants the "Chill" activated ability, which when used, will prompt the player to pick a tile to cast the ability on. This tile must be a visible square and cannot be further than 8 tiles from the player.

Using Chill will create a 3x3 area of that lasts for 3 rounds, centered on the chosen tile. Any creature that ends their turn within the frozen mist will suffer cold damage and a significant temperature decrease as determined by mutation level. Three different damage rolls are calculated for all 3 rounds that the frozen mist is active, where the damage rolls get higher every round. After 3 rounds, the frozen mist will disappear.

Formulas
The following formulas are used to determine damage (rounded up) and temperature decrease based on mutation level.

Advantages

 * Deals remote damage and can decrease temperature, causing creatures to become frozen
 * Decent area of effect
 * Lasts for multiple rounds before disappearing

Disadvantages

 * Very high cost at character generation
 * Relatively poor range
 * Creatures will often path around the frozen mist if it isn't cast directly on top of them
