Daernius´s Spell Rewrite

You attempt to alter the effects of a spell that is being cast by a creature. If the creature is casting a spell of 5th level or lower, the effects of the spell are replaced by a random spell from table 0.1. If it is casting a spell of 6th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and its effects are replaced. You decide the new objective for the rewritten spell but it is cast as if you were in the space of the creature who originally attempted to cast a spell.
