A mass of tiny insect-like mechanical creatures surges closer.
A clockwork swarm regains 3 hit points per round. Damage dealt from acid, cold, or fire effects cannot be self-repaired. If a clockwork swarm takes damage from an area attack, it is unable to repair itself for 1d6 rounds following the attack. If reduced to 0 or less hit points, it regains 1 hit point per round (but still cannot repair damage caused by acid, cold, or fire effects) until it has at least 1 hit point (at which time it begins to self-repair at its normal rate of 3 hit points per round).
