Fight against Bangungot, you must deal at least <x> damage or she will recover some HP at the end of the round.
Several Bangungot's Mananaggal may spawn along with Bangungot, the number that spawn increases according to <something>. Any that you do not kill will remain in the room in subsequent iterations of this phase.
Things to watch out for are LoV, and quicken/powerup when it gets low. Otherwise it is fairly easy.
If Bangungot dies, advance to Phase 3.
Phase 2B: Rescue one of the patients (2~3 Minutes)
You will be moved to another identical location on the map. The Bangungot you were fighting still exists and maintains its previous HP value.
Bangungot (invulnerable) will spawn at the center of the room and cast full heal. (dont waste time trying to kill it)
All players will be resurrected with 1 health and moved near the portal.
When they have all died, you will return to Phase 2A.
Phase 3: The Pillar of Spirit (1 Minute)
This is where you are successful of defeating Bangungot in Phase 2A. But in order to eliminate it completely, you must defeat the Pillar of Spirit.
The Pillar of Spirit has a max HP of 250 with 1 damage taken (similar to plants and mushrooms).
If you fail to defeat it within a minute. Bangungot will be fully resurrected and return to phase 2A. (the remaining HP of the pillar of spirit will probably be saved for a future iteration of phase 3)
Easiest way to kill it is Genetic's Blood Sucker. (This does not instant kill it anymore) Still good thing to use as it procs stuff like CD in mouth.
