Ripper Drone (5e Creature)
From D&D Wiki
Small construct, unaligned
Multiattack. The ripper drone makes one claw attack, and use the Self-Replicate action, if it can without reducing itself to or below 0 hitpoints.
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage. If the target isn't a construct, plant, undead, or ooze, the drone regains an equal amount of hitpoints.
Self-Replicate. The ripper drone takes 5 necrotic damage, and creates a second ripper drone, appearing within 5 feet of the drone which spawned it. It only has 10 hitpoints, and has a maximum of 15.
Few constructs are as disgusting in nature compared to the ripper drone. From a first glance, they're simple, made up of interlocking plates and razor sharp claws. However, this all changes in reaction to blood.
When exposed to blood, their bodies balloon as it quickly absorbs into the steel. Even worse, this causes them to, in a sense, reproduce. Thanks to this, a single drone can lead to infestations, as they simply keep on multiplying.
God only knows how they come about. Some believe they are the deranged creations of insane artificers, others have theorized that they are punishments from the plane of Mechanus. No matter how they come about, the destruction brought on by them is horiffic.
