Photosynthestrike

The Photosynthestrike is a Pre-Hardmode magic weapon dropped by the Vinewrath Bane. On used, it rapidly fires a solar bolt that homes in on enemies and can pierce for up to two enemies at a time.

Trivia

 * Its name is a portmanteau of the words 'Photosynthesis', which provides light energy from sunlight, and 'Strike' which is a sudden attack.
