Amidias' Spark

Amidias' Spark is a Pre-Hardmode accessory dropped by Cnidrions in the Underground Desert. When equipped, the player will release 8 gravity-affected sparks around them when harmed by any source of damage. These sparks linger for 2 seconds, partially ignore immunity frames, and deal 6 damage in Pre-Hardmode which is buffed to 36 in Hardmode.

Amidias' Spark also has a rare item variant called The Transformer that also drops from Cnidrions.
