Notes
- After firing a Concussion Grenade, the grenade impeller gains
and becomes disabled for 1 turn. - Concussion Grenades gain About to Explode after being left on the ground for one turn. Picking up the grenade in this state will lead to it exploding in the owner's inventory at the start of the next turn.
- Concussion Grenades gain
on Tactician or Honour Mode, preventing them from being picked up entirely.
