Even if you don't participate in the Black Beast Dormeho raid you still get EXP and the Black Beast Slayer Stamp(s) (yes, you can get extras) if enough were defeated. The stamps go away upon relog and don't stack, but the mass EXP is giving EXP from the event to any and all characters who have or haven't participated in the event.


UPDATE: This only applies to characters who have participated in the event before, apparently, and it doesn't necessarily mean they had to have stayed there for the end of it.

These should be corrected.
