Strife

Strife sits on an individual Invader, not on the land, and can't be added where there are no Invaders. When an Invader with Strife would damage the land or Dahan, remove one Strife and it deals 0 damage instead; the Dahan still fight back. Strife has no effect when Invaders damage other Invaders. It moves with its Invader and goes back to the supply if that Invader is removed or destroyed, and an Invader can have more than one.
