Location: From the Last Bridge - 2e 2n e n 2e open irondoor 3e 2n.
Strategy: Priest is soloable by any class. Just try to avoid his spells, because he blinds. Priest is perma-sanced, so don't use powerful spells like fireball or harm. The main danger when doing priest is the possibility of being trapped by other side players (e priest zone is active PK area).
So the easiest, fastest (and safest) way to kill priest is to break both doors, blind priest and shoot him dead. Sometimes he loads shadow which is hard to do with defence warrior (must be legend with ob set and with ob sword, and will end on wounded/bad which is dangerous in pk area).
After last change priest calls orc guards from irondoor, so either kill them first (hard to stab though, but possible to shoot|hit/flee), or block door before guards come.
Portable rooms: Bell Tower and Guardroom at irondoor.
Level: Any legend level player (may be slow with some classes).
Loads: Fang, purple scroll (loads in priest's hand), black arm wrappings, antidote bottle in pouch.
