A light weapon?
I am loving all of the Orcs Must Die! weapons and spells! Almost everything has been covered---fire, ice, air, lightning, necromancy, vampirism, even poison! I especially like how each spell has a unique primary attack. The Flame Bracers shoot a fireball with splash damage, the Ice Amulet fires a tripleshot of ice, and the Ring of Lightning fires a bolt that chains to nearby units.
But there's one weapon that's missing from the game---light! How about a light wand or something that shoots a continuous beam of focused light ahead of you? It could be a more or less weak, yet precise weapon good for killing kobolds from long range.
The secondary could be something unique too, like a temporary light force field that could act as a barricade in a pinch, or a wall that stunned enemies that entered it.
Anyway, what does everyone think? Wouldn't a light weapon round out the elemental weapons perfectly?
