Conjure Beast

You call forth a beast of CR 4 or lower that appears in an unoccupied space within range. The beast disappears when it drops to 0 hit points or when the spell ends.

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

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

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the challenge rating increases by 1 for each slot level above 4th
