Unsummon

Roll 6d8. You choose up to one summoned creature with less then that much health that you can see within range. Its controller must succeed on an Constitution saving throw or have the creature be returned to it's plane of origin. When it does, it and anything it was summoned with it get sucked up into what was used to summon them (eg: wizards hands, magic amulet). If a magic item was used this way, it regains all charges. The summoner becomes stunned until the end of its next turn. 

At Higher Levels. You may choose an additional target and an additional d8 for each level this spell was cast at (two targets at level 1, three at level 2, etc).
