Wand of Frosting

The spark bends slightly on the way out and dies after a set distance, so it wants targets at close to middle range rather than across a room. What earns it a slot is the crit rate, which starts several times higher than a weapon normally does, plus a good chance of leaving a burn on whatever it touches.

Mana barely matters here. It costs so little that you can hold the button down through an entire fight without touching a potion, which counts for a lot at the stage of the game where your mana pool is still tiny and every other option drains it in seconds.

Because the natural crit is already high, modifiers that push crit further pay off more than usual, and the ones that would touch knockback or mana cannot roll on it at all. In a Remix or Zenith world it is reworked substantially, since the wand it upgrades from is not available until the walls go up there.
