Rule Name:Invisible Combatant
An invisible combatant gains a +20 to their strike chance to hit targets who are aware that the invisible attacker is there, but can't otherwise see them. This bonus is cumulative with normal Surprise bonuses if this is the first attack. Thus, an invisible attacker who sneaks up on a completely unsuspecting person gains a +45 to their attack and the target gets only magical DEF.

Someone in combat with an invisible opponent must make a PER roll for each attack.
  • 1x PER roll - Attack normally with no modifier
  • 2x PER roll - Attack at -10 to SC
  • 3x PER roll - Attack at -25 to SC
  • 4x PER roll or worse - Unable to sense them well enough to target them.
