So this expedition I just started is going to be actually impossible to complete as one of the monsters I need to kill spawned out of bounds, tried pulling it with cc throwing ranged abilities on it and agro it so it maybe comes back in bounds but nothing seems to help so this one's doomed to fail.

EDIT:
By sheer RNG it managed to walk close enough to the wall that it counted as in bounds of some sorts so I managed to kill it with the outer range of my blade of storms lol. Took a good while because bleeding edge couldn't reach and debuffs didn't seem to apply either but it's dead somehow.
