The magic missile ray does (xplev/2+1)d6 damage, so higher-level spellcasters can deal significant damage with this spell. A level 30 character deals 16d6 damage with magic missile, averaging 56 damage per hit. The damage can be doubled by using walls to reflect the ray again to the target, hitting it twice. This spell's damage is doubled for Knights by carrying the Magic Mirror of Merlin. Note that this is different from the wand of magic missile, whose damage is a fixed 2d6.
