Slime Staff

The Slime Staff is a magic weapon that summons a baby Slime minion to fight by your side. The Slime Staff is currently the rarest dropped weapon, with a drop rate of 0.01% (1/10000) from most Slimes and the Slimed Zombies.

The best possible modifier for this weapon is Ruthless. The Mythical modifier provides a wider array of stat bonuses, but these mostly pertain to the initial summoning and not the resulting Slime. Additionally, minions cannot critically hit.

Tips

 * The Slime Staff can be obtained before Hardmode. An easy way to obtain the Slime Staff without much effort is to construct a statue farm with one or more Slime Statues, leave it alone for awhile, and occasionally check if the staff has been dropped yet. Another good way of farming these is killing king slime many times as it creates and spawns slimes that can drop it.

Trivia

 * The staff itself may be a Shillelagh.
