You envelop yourself in an impenetrable bubble of divine energy, a sanctified shield that renders you impervious to harm.
You take no damage, but cannot attack while in the bubble. You can heal others though while in the bubble.
If you taunt another creature to attack you, they can attack another creature while you are immune, unless the target is charmed or dominated in some way.
The bubble can be dispelled, because it is magical by nature.
A radiant sphere of divine energy envelops you, shimmering with sacred light. Intricate patterns dance across the bubble’s surface, its impenetrable barrier glows intensely, repelling all forms of harm.
