Blessed Emanation

You surround yourself with a glowing divine 30-foot Emanation.  This powerful emanation causes the caster, the area around them, and their allies to glow with a dim light. The color should be befitting to the god that the caster worships. A goodly aura might emanate a golden yellow glow where as an evil god emanation might be a dark red. 

After the initial "ally" or "non-ally" decision is made on any target effected by this spell the 1st time they enter the aura (a free action) if you decide to switch someone from an ally to a non-ally or vice versa you must focus on them to make the change, which requires a bonus action. You may switch any number of targets during this bonus action. Each Ally within the radius receives the benefit of the Bless spell.

Bless: Whenever an ally within the radius makes an attack roll or a saving throw before the spell ends, the target adds 1d4 to the attack roll or save. The first time anyone enters the aura you decide if they are an ally or not. Should they move outside the aura the effect ends on them, but as soon as they re-enter the spell takes effect on them again as an ally if they were initially chosen as an ally.

Special: This spell counts as the Bless spell and any effects that specifically mention or effect the bless spell also effect this spell the same.
