Would be nice to see a different color set and animation linked to the Cleric's deity, to give diversity to that spell. Example, Beryl could be a multi color prism crashing down on the ground with a blinding light. Vorax could be a Huge blood red Axe that swipes down (don't know if that's feasible) etc. I know there's different Animation available for GM's entrances, and they are customizable, maybe that system could be adapted for the Hammer of God spell?
