|A wooden cudgel, loaded with more than just lead.|
+6 shillelagh (8 damage, +3 accuracy, 130% speed)
Causes explosion (somewhat like a smaller, weaker Shatter) on attack
Despite everything blowing up in your face constantly, it actually doesn't do much in the way of backlash damage, particularly if you're playing a high-AC character. It's especially useful for quickly clearing out swarms of fragile enemies like bats or killer bees, but it deals with single enemies in the early- and mid-game just fine. It does make plenty of noise, though, so expect to deal with swarms of enemies considerably more often.
Prior to 0.15, Devastator had a +4, +8 enchantment level.
