Equanimity

Equanimity is a craftable Hardmode rogue boomerang. It automatically throws a series of returning light/dark disks that pierce infinitely. When contacting an enemy, several light and dark shards are released from the disk that deal 10% of the disk's base damage.

Performing a stealth strike with the Equanimity will cause the next boomerang thrown to release additional light and dark shards.

Trivia
