I would absolutely love to see Celestial essentially make any AST card buffs into an AOE effect, but at their current level/intensity.

For example: You throw an Enhanced (effect increased) Balance on your groups' top DPS, use Celestial and that Enhanced Balance extends to all people in the area of effect. Essentially, like Royal Road but without the decrease in power.

This would be in addition to the two effects it already has (stun and 5 second buff extension).
