Darkmaster not spawning

so i clear the whole instance even resetting it and darkmaster does not spawn when you clear the instance

I’m having the same issue.

are you entering Scholomance of old?

(via the book at the entry?)

I’ve never had any issues with getting him to spawn.

There are one of two possibilities.

You’re either in the wrong instance, or there’s a boss you haven’t killed in order to spawn him.

ok i figured it out

one of the shades that spawn from the top right thats immune to physical transformed and i had to equip shadowmourne just to aoe and kill it and once that npc died darkmaster spawned

It’s Old Scholo via the book. Has has spawned in the past, but has stopped even after slaughtering the other bosses. But I will check Dabdaddy’s advice the next time I’m in there.

In the final room where he spawns kill all the npcs flooding the rooms and with the bosses dead he will spawn

All trash in the rooms must be cleared as well. There’s a zombie in a little alcove i missed before on polkelt.

I wandered back in to OS and murderhobo’d every single thing in those 6 rooms and he spawned. Dunno what I missed in other runs.
