You summon a black pudding that immediately attacks creatures near it. You have no control over the creature, and it may attack you if there are no more obvious opponents. The black pudding is treated as a summoned creature and has the extraplanar subtype. The black pudding’s split ability works normally, but all puddings derived from the summoned one disappear when the spell ends.

Mythic Conjure Black Pudding

The black pudding has fast healing equal to your tier, as do any puddings that split off from it. The black puddings from this spell never attack you, though they're otherwise uncontrolled and might attack your allies if there are no other obvious opponents.

Augmented (6th): If you expend two uses of mythic power, the pudding gains the savage mythic template. Puddings that split off from the giant pudding don't gain the template.
