Myth of Magic

At 2nd level, when choosing this archetype, you can cast the spell protection from good and evil, (your spellcasting ability for this spell is Intelligence) targeting yourself. You can cast this spell once, then you regain its use after you complete a short or long rest.

In addition, when using the Detect Weakness feature, attacks that benefit from the damage bonus provided by the feature are considered magical in order to overcome fiends’ damage resistance and increase by a die step if the feature is used against a fiend (1d4 increases to 1d6, 1d6 increases to 1d8, etc.).
