Zecui
Level 6Attacks
Abilities
Trigger A living creature within 30 feet is reduced to 0 Hit Points
Effect The zecui channels corrupt vitality into the triggering creature, which still goes Unconscious but does not gain the dying condition. While that creature is unconscious, the residual energy attempts to counteract any vitality spell healing that creature with a counteract modifier.
Frequency once per round
Effect The zecui makes two shortsword Strikes against an Immobilized or Off-Guard target. These strikes count towards the zecui's multiple attack penalty, but it doesn't increase until after the second attack.
The zecui fuses much of their chitin into a black metallic shell. They gain resistance 5 to all damage (except mental and spirit) until they next take a move action.
A creature hit by the zecui's spit attack is Immobilized by the larva-infested mucus and stuck to the nearest surface until it . While that creature is immobilized, it is exposed to zecui larvae at the end of each of its turns.
Saving Throw DC 25 fortitude

Stage 3 Drained 2 (1 day)
Stage 4 Drained 3 and controlled by the zecui larva (1 day)
Stage 5 the creature dies and the adult zecui can emerge from the corpse as an Interact action
These chitinous entities can only grow to adulthood within a host creature, usually a humanoid or larger animal. When such hosts are particularly plentiful, zecuis can multiply at a horrifying rate, sealing hosts in subterranean chambers until their larvae grow to adulthood. However, during lean times, zecui adults will sate their hunger by eating those hosts along with any unlucky larvae gestating within, unable to be infested by their own young.
Between periods of wakefulness, zecuis hibernate for decades in burrows or buried within the soil. Sometimes an unincubated larva will be buried this way, waiting for a living host to come in contact with it. Once a zecui larva has gestated long enough to take control of its host, it may seek out larger and more powerful entities to devour the host, transferring themselves to a more plentiful source of food.
