Malice is an enemy substance in Breath of the Wild. It is a black and purple substance found throughout the four dungeons of the Divine Beasts and Hyrule Castle. Touching the substance will damage Link. Small eyeballs can also appear with the corruption; particularly within the dungeons. Destroying the eyeballs will remove the immediately surrounding Malice.
Cursed heads of Stalkoblins, Stalizalfos and Stalmoblins can appear from areas of Malice, which have a total of 30 health each, and will repeatedly respawn until the particular section of Malice is destroyed.
