GM BLOG The Battle of Crimsonwood Keep

The 5 weapons glowing could represent a room for each class like the thief room has monsters that a hermit/NL could take a hit and the warrior room could need different elements hence including paladins, this may apply to a mage room too ,what i mean is that the statue may be killed in parts with each of the five classes killing a part of the statue, anyways it looks great and i think i should keep on leveling too.

Just wondering, but what makes a room unique that only a hermit/NL can do, and not an archer?
