A spell using the tumultuous spell metamagic feat propels an enemy 1d4 x 5 feet without triggering AoOs. The spell blast revelation from the oracle’s apocalypse mystery allows the oracle to bull rush enemies whenever one of their spells crits on a target.
Which effect would go first? Could they happen at the same time? If an oracle with the greater bull rush feat procs both effects, can an AoO still trigger?
