Conjure Astral Familiar

You call forth an elemental servant. Choose an area that fills a 10-foot cube within range. An Astral Familiar you have access to appears in an unoccupied space within range. 

The elemental is friendly to you and your companions for the duration. Roll initiative for the elemental, 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 familiar, it defends itself from hostile creatures but otherwise takes no actions.

If your concentration is broken, the Familiar doesn't disappear. Instead, you lose control of the Astral Familiar, it becomes hostile towards you, nearby creatures and your companions, and might attack. An uncontrolled familiar can't be dismissed by you, and it disappears 1 hour after you summoned it.

The GM has the Familiar's statistics.
