Space Gun

This weapon uses 7 mana and shoots very quickly. Each bullet inflicts about 25 damage to a monster. This gun has no selling value to the merchant.

Since the gun uses mana as ammunition, if one wears a full meteor suit and several bands of starpower, it is, in theory, possible to have unlimited ammo.

(Mana doesn't regenerate while you use it, so it is impossible to have unlimited ammo, although you can gain back the mana quickly.
