Chi disappears, not buffs. And like I said. Even if there was a mob skill which purges person, there is no guarantee that it would target quest activator. Can target random person just as good.
make an instance or a random room inside one of the old CTF rooms which has a random mob aoe purging + an exit NPC ( yes i am the best ever lmao ), add 20 second timer so that some kid does abuse that in the middle of pk or someshet
