Exorcist

Learning of the denizens of hell has made you a master of destroying beings of the lower planes as well as other evil spirits. Your drive may be from a past experience with the forces of evil, or rather a drive to help the innocent. No matter the reason, your skills get the job done.

Exorcism

At 3rd level you have learnt to harness an ancient ritual, you drive out evils spirits and energies from a person or object. This ritual can be used offensively to harm opponents, it is especially effective against fey fiends and undead.

Exorcist's Mark

At 7th level your focus and practice have paid off with the development of a technique to harm and weaken the forces of evil. Any the target takes additional Radiant damage equal to your strength + your proficiency bonus

Area of Expertise

Starting at 10th level you gain resistance to damage from fiends fey or undead. You also gain advantage on saving throws against being possessed or cursed.

Bane of Evil

At 15th level you learn to increase the severity of your exorcisms. Your radiant damage ignores resistances when used against those susceptible to them.

This ignores immunity at 18th level.

Last Rights

At 18th level, if an evil aligned creature is present, an attack that would reduce you to 0 hit points instead reduces you to 1 hit point and gives you one turn immediately where the only actions you can take are "Exorcism" or "Exorcist's Mark"
