Didn't get the bow of order till late in the game. used it to get rid of red crystals on towers that I forgot about. it made a 6 second flight before hitting the targets, took two shots to destroy. awsome range! used dragon flight in the flesh mage palace to destroy golems. has a blast radius that may bite you if you're not careful. liked Demise for the close up work. 29 hp packs a punch. Storm might be my favorite though. after it hits, lightning leaps out of your target and damages anything else nearby. neat f/x.
the little 9hp short bows ice fist and fire xxxx have the most power for price. usually 4 or 5 shots are enought to finish off most npcs. a comparable 14hp bow may take 8 or 9 hits for the same total damage. pick em up, they're cheap and effective.
