Book of Vile Darkness

One living creature touched must make a CON save. On a failed save, the subject's skin turns red and blisters. The blisters quickly turn into oozing wounds. Furthermore, the subject's sense of self becomes strangely clouded, diminishing her self-esteem. The subject’s STR score is reduced by 1d6 and their CHA score is reduced by 1d4 for 24 hours.

Corruption Cost: 1d6 STR damage

Any spellcaster that prepares spells can learn these spells. Each spell list has an alignment attached to it. If a creature of a different alignment casts one of these powerful spells, their alignment shifts towards the alignment of the spell by one step. Each spell has a corruption cost that is paid when the duration of the spell ends or according to the spell’s description. If the cost is ability damage, it is restored when the caster finishes a long rest. If the cost is ability drain, it does not recover until the creature receives attention from a Greater Restoration spell.
