Emerald Staff

Item Info
The Emerald Staff is the third best staff of the gem/bar combinations and can be rapidly cast due to its low mana cost. It can be acquired early in the game and also does a decent amount of damage.. It can pierce up to 3 enemies (unlike the Amethyst staff that can only hit one).

Due to its low mana cost, it is unable to support the Mythical modifier because of rounding issues. Therefore, its best modifier is Godly or Masterful.
