Can the walls of a waller elite be broken?
Can the walls erected by a "waller" elite monster type be destroyed using attacks or any thing else?
No you can't destroy it. But for example leap allows you to escape. Or I figure teleport could work as well.
NB. "Champions can only create short, straight walls, while Bosses can create three-sided rectangles that box fleeing players in, forcing them to run back past the boss and other monsters to escape."
from here.
Sure can. At least, they can with this stuff:
Bottomless Potion of Kulle-Aid
OH YEAH!
