Conjure Infinite (e)

You call forth a servant. An anything but undead of challenge rating 16 or lower. For example, a fire elemental emerges from a bonfire, and an earth elemental rises up from the ground. The servant disappears when it drops to 0 hit points or when the spell ends.

The servant is friendly to you and your companions for the duration. Roll initiative for the servant, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the servant, it defends itself from hostile creatures but otherwise takes no actions.

If your concentration is broken, the servant doesn't disappear. Instead, you lose control of the servant, it becomes hostile toward you and your companions, and it might attack. An uncontrolled servant can't be dismissed by you, the only way to dismiss it is to eliminate it.

The GM has the servant's statistics. Sample servants can be found below.

For every Rating below ten; add 1 extra creature/summonable
