Orbalisk Swarm
✨
A crawling carpet of dark-side-sensing parasites that latch onto everything in reach and infest hosts with a wasting plague.

Detect Dark Side (Trait). The orbalisk swarm can sense the presence and location of any dark side aligned creature within 300 feet.

Swarm (Trait). The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a tiny orbalisk. The swarm can't regain hit points or gain temporary hit points.

Multiattack (Action). The Orbalisk Swarm makes two Attach attacks while it is above half HP, and one attack while below.

Attach (Action). Melee Weapon Attack: +6 to hit, reach 0 ft., one creature. Hit: 13 (2d8 + 4) kinetic damage, and a small portion of the swarm attaches to the target. Once attached to a target, those orbalisks begin to reproduce through fragmentation. Whenever the host completes a long rest, they must make a DC 14 Wisdom saving throw. For each saving throw the host fails, the size of their Hit Dice is reduced: from d12 to d10, from d10 to d8, from d8 to d6, from d6 to d4, or from d4 to d2. If the host fails a saving throw while their Hit Die is a d2, they die as the orbalisks consume them.
