The Rafter in the Nebezzdos sewers can get killed by nightrisers.
I'd like to suggest, for convenience sake, that this not be the case!
Is there even supposed to be a rafter that goes from the morass to the Nebezzdos sewers? I've gotten conflicting responses regarding this.
Alternatively, perhaps instead of the rafter landing in the Nebezzdos sewers, have him land where there are no hostile spawns? Like the lovely beaches of Murdertown.
It shouldn't be a cake walk to just trek into the enemy territory, Caster. When I walk my Mortal to Mistlocke for scouting, I'm not expecting margaritas and fresh bbq as I enter hostile territory. Lol.
I think the Rafter is perfect. When/if he dies, think of it as relief from enemy visitors.
make him immortal and turn off his AI.
