Whenever a Survivor fails a Skill Check while repairing or healing, Undone gains +3 Tokens, up to a maximum of 18/24/30 Tokens.
Performing the Damage Generator action on a Generator consumes all accumulated Tokens and applies the following effects:

• Instantly regresses the damaged Generator by -1 % per Token of its total Progression.
• Blocks the damaged Generator for 1 second per Token.
• Causes the damaged Generator to start regressing once it becomes unblocked.
