Gripmaster

The Gripmaster hovers over the player. After a while, it will attempt to grab the player. If the player is successfully grabbed, it will shoot the player to a previously cleared room, which will be reset and have all enemies respawned. It automatically dies if all other enemies in the room are killed. Gripmasters deal no damage, even if jammed.

Gripmasters also have a small chance to pull out a pistol and shoot in all directions. When this happens, Gripmasters need to be killed normally to clear the room.

Gripmasters don't appear in any specific layouts, instead having a low chance of replacing a random enemy, usually the strongest one in the room, on any floor similar to Confirmed. If the player is successfully grabbed and shot out of the room, the Gripmaster won't reappear if the player re-enters the room it was in.
