Potion of Corrosion, Brewed with Awkward Potion + Acidic Mass. Gives the consumer corroded for 3min. Can be upgraded to 8min

Corrosion Antidote (name probably needs work) Brewed with Potion of Corrosion + Fermented Spider Eye (or alternatively Essence of Purity). Could either be one use and removes corroded when consumed or splashed. Alternatively, it could apply a buff that removes corroded for the duration of the buff.

I like the idea of the Potion of Corrosion, however, I'm not very keen on an antidote.

Okay sure, I did not know if Sculk Spitters Were supposed to be as powerful as they are.
