unholy champion (revised)

as with many holy people they incorporate the attributes of there gods both there positives and negatives and with that devotion gains strength to smite your gods enemies. To gain this feat you must of been a devout follower of your god for a minimum of 1 week.

Positives

• Your attacks are considered magical for overcoming resistance.
• When striking a supernaturally evil or good foe (creatures included in the 'protection from evil and good' spell) including beings with magical spell casting of divine and arcane of an opposing alignment (all spell casters in the other two alignments except yours). When you strike a creature with a physical or ranged attack depending on your alignment you deal an additional 1d4 radiant (good) or necrotic (evil) damage this damage increases to 1d6 if you are attacking while wielding an item favoured to your god (this can not be your spellcasting focus).
• You gain plus 1 AC while fighting against your supernatural foe and/or casters.
• you may cast the spell 'protection from evil and good' upon yourself once per long rest at its lowest level.

Flaws 

• if you turn away from your god or do something negative in the eyes of your god the positives of this feat becomes inert.
• until you gain back the favour of your god or gain the favour of a new god,once per day the GM (Game Master) can force you to make any roll with disadvantage. 
• if you change gods this feat can not be regained until a week has passed in the presence of your new god.

(got the idea from savage worlds edges)

this is the revised form.
