Cave Rippers are small, twisted humanoids with tough, leathery, pale grey skin. They have long arms and fingers tipped with razor-sharp claws. 5-10 [d6+4] of the creatures will travel in a pack and can be found roaming the underworld in search of weak prey to devour. Their favored means of attack is to swarm a target and repeatedly claw it until it is dead. Up to four of them can swarm a normal-sized human target, two for smaller races like Dwarves or Halflings. A successful roll to-hit against a target means they have latched on that round, doing no damage but gaining +2 to-hit and doing full claw damage in subsequent rounds. PCs can remove up to two attached Cave Rippers per round, with a successful roll to-hit both creatures are flung away, but only one of them will take damage. Note that this applies even to fighters of 2nd-level or higher – a fighter’s multiple attacks per round apply only to non-attached Cave Rippers.
