Whenever a character's HP hits 1/8th their maximum, their HP is considered "critical". When this happens, there's a 1/16th chance that the character can use a desperation attack called an "Atrophy" instead of a normal attack.

Atrophies, more often than not, deal a literal ton of damage to one or more enemies in range. This is to make up for the fact that they're rarely seen.

Below is the complete list of Atrophies for each playable character in Hallowed Ultimatum. Use your browser's search function to find a specific Atrophy.

NOTE: "L" in the damage field refers to your character's current level when using the Atrophy. Example: your Atrophy's damage is 2Ld10 and your current level is 50. For your damage, you'll roll 100 d10. See why it's so rare to see an Atrophy in action?
