Team Wound punishment mani_tk_team_wound_reflect turns the functionality on and off
mani_tk_team_wound_reflect_threshold sets the number of team wounds required by a player during the course of a map before the reflective damage kicks in
The mani_tk_team_wound_reflect_ratio cvar is a damage multiplier that inflicts whatever damage (armour loss + health loss) was given to the victim back to the attacker.
When set to 1.0 the damage is perfectly reflected, set at 2.0 the damage inflicted back on the attacker will be twice the damage etc.
An additional cvar mani_tk_team_wound_reflect_ratio_increase increases the reflection ratio each time the player team wounds another player.
This is to deter persistent team wounders.
