Morth (5e Creature)
From D&D Wiki
Tiny monstrosity, unaligned
Aggressive. As a bonus action, the morth can move up to its speed toward a hostile creature that it can see.
Cling. Melee Weapon Attack. +0 to hit, reach 0 ft., one creature. Hit: On a critical hit only, the creature takes 1 piercing damage. On any hit, the morth "clings" and becomes physically attached to the target, and the morth's speed becomes 0 feet while clung; it occupies the target's space and moves with it. While the morth is clung to the target, the target's attack rolls have disadvantage against the morth, and the target's speed is halved. Multiple clung morths can further halve the target's speed (reducing it to one quarter, one eighth, and so on), but cannot reduce the target's speed below 5 feet. The morth can no longer cling if it is reduced to 0 hit points, or moves away from the target. Any number of clung creatures are removed if the target creature takes an action to remove them.
A morth appears as a black sphere with numerous protruding orange barbs, and a single large eye with a green iris and a crimson pupil. It is only about the size of a mundane rat, and is only capable of moving with erratic hops. Despite its dangerous appearance the creature's barbs are intended to cling to the hide of other creatures, much like a burr, rather than to stab and inflict damage.
Weaponized Offspring. Morths are the newborn offspring of mothula, comparable to either eggs or larvae. Their primary purpose is to slow down and hamper any and all creatures they come across. They seem to do this to make prey easier for their parent mothula to hunt down, or to prevent predators from giving effective chase. Morths do this even if there is no mothula present, acting entirely on a very basic instinct. Morths are usually only found in the vicinity of mothula, which inhabit forests or marshes. They are typically born in large swarms, and it is exceedingly rare for any of them to reach adulthood.
- Swarm of Morths, a morth swarm capable of immensely slowing down any creatures that pass within range
- Mothula, the parent of this larval creature
- Great Mothula, a more powerful form of mothula capable of innate spellcasting
- Gel, a similar Tiny creature which only attacks by slowing down larger creatures
