Corrosive Sculk

This mod gives Sculk a corruptive property that will temporarily drain your health.
If you have played any of the new Zelda games, you may notice that this is inspired by Gloom from Tears of the Kingdom:

Players and mobs will take sculk damage if making contact with sculk or if attacked by any sculk-themed mobs (e.g. the Warden). The only way to heal from the Corrosive Sculk effect is to bathe in natural skylight; and don't try using Absorption hearts, it won't help much.

For more prolonged periods of time in the deep dark, it may be in your best interests to create a Potion of Sculk Resistance. Sculk Resistance is brewed like any other potion by using a Sculk Catalyst in an Awkward Potion, and grants temporary hearts that can tank sculk damage which regenerate without the need for sunlight.

Sculk Resistance has 3 tiers, each of which adds one resist heart per level, and can be obtained by adding glowstone.

If you're a builder who wants to use Sculk in your palette, you can craft it together with wool to create Woven Sculk: a variant of Sculk and Sculk Veins that appear identical to their normal counterparts, but will not damage you, making them a perfect building block for your next Warden Petting Zoo.
