first good response i've seen. was gonna sound off on the same idea.
When you first attempt the Burial Chambers, thats where they are useful.
Coming down off the ramp, immediately toss a pile in the doorway(s) that doesn't have a door.
Clearing passages as well, opening the first door off the ramp, typically a hall with a open doorway to the left or right. Perfect time for woodpile CC lowbie tool.
Proved invaluable against my first 2 star skele archer, who put me down first. My first time in that backwards dropping stoneslab hallway. The archer and his two melee buddies were camped out, and clipped me trying to get away. I had thrown down a wood pile just at the top of it to block pursuers. And absorbed several arrows when I returned for vengeance. Can double as a door back-stop. Mean skele cut you? run, close door, set woodpile. Let them chop through it all. Time enuff for fleeing.
Then again with my first encounter with green skele. He hit it two or three times and destroyed it. Luckily I had a spare with me.
Which brings me to the most basic point, and use. Cheap walls. Wood Piles are as versatile as the mind using them. When used properly they can be the general in the field.
