I infiltrated Revan's secret archive and found some notes on our enemy's abilities. Here they are:
Three actions.
1) Penetration (passive). When attacking from behind, the critical hit chance increases to 100%.
2) Mania (passive). After each action, it laughs loudly, reducing all stats of all opponents within a radius of 2 by 1-3 until the end of the battle.
3) Not a chance! Jumps up to 6 meters and grabs a flying opponent by the butt. Interrupts the Flight action, deals 50% damage, and deprives all targets of actions for the next turn.
4) Cleave. Kills the opponent. Available if the target has less than 50% health.
5) Mega-cool swing. Deals 90% damage to all enemies within a radius of no more than 1.
6) Suppression. Deprives the target of all action points for the next turn. Radius 1-3.
7) Psychos don't die. Restores 100% health and loses one action until the end of the battle. If the total number of actions becomes 0, it dies.
8) The maniac will only kill himself! Can only die from the "Psychos don't die" ability.
9) No resurrection! Absorbs the corpse of a dead opponent and gains +50% damage on the next damaging action.
10) Only I am charismatic here! Resets the opponent's charisma, after which they flee the battlefield. Radius 1-10. Applicable only to targets with charisma of at least 40.
