The Effuser

The Effuser is a craftable Hardmode radiant weapon. It rapidly swings out an effusing mace in an inaccurate fashion, which can extend up to 22 tiles before returning and damages and pierces enemies. The first successful strike in an attack releases two to seven lingering mist particles that heal players they touch equal to the attacking player's bonus healing. Up to ten healing mist can exist at a time, and it disappears after 10 seconds.
