Nidus/Abilities

Adaptive Carapace
Nidus possesses hyper-metabolism allowing him to passively regenerate ? health per second.

Additionally, enemies damaged by his abilities generate 1 Adaptation Point per enemy to fill an evolution gauge displayed above the ability icons.
 * The evolution gauge can be filled by 10 Adaptation Points, resetting upon completing 1 Adaptation Stack with the center of the guage displaying the next stack number; up to 4 Adaptation Stacks can be attained.
 * Each completed stack causes parts of Nidus' carapace to open, revealing the writhing infested flesh beneath.
 * At stack 4, Nidus can expend all Adaptation Points to use the Infest ability, emptying the evolution guage and revert Nidus to stack 1.

Abilities

 * Rupture - Nidus stomps the ground to unleash a linear growth of infestation in front of him. Each enemy hit by the infestation increases the ability's damage on subsequent enemies, as well as refund an amount of energy per enemy hit/killed.
 * Tendrils - Throws an infestation pustule at the targeted location that erupts into a mass of tendrils on impact. Tendrils launch in all directions grabbing enemies in range and clustering them together in a ragdolled state for the ability's duration.
 * Symbiotic Link - Nidus tethers a strand of infested tissue to a targeted enemy, disabling it completely and redirecting all damage received by Nidus to the target for the ability's duration. Ally target eligibility has yet to be showcased.
 * Infest - Once Nidus accumulates 4 Adaptation Stacks, he can expend all stacks to create a large patch of infestation in the surrounding area. Infestation pods erupt from the infested terrain and spawn swarms of Maggots that latch onto enemies to stun them continuously before exploding for damage, which also generate Adapation Points. Nidus heals at an accelerated rate when standing on infested terrain.
