Conjure Aberrations

you point at a spot within range and evoke Eldritch words only understood by those you summon. that point suddenly begins to have a crack of your choice of color and is either on a solid surface or simply emanating for empty space it self. this is a portal to the far realm, that brings forth unimaginable creatures, any enemy within 10 feet of the point must succeed on a wisdom saving throw. on a failure a creature takes 3d6 psychic damage and becomes Frightened, on a success it only take half damage and is not frightened. you summon either a single Aberration monster of Challenge rating 5 or lower such as a Chuul, Spectator, or Grell or if you choose to use multiple Emeralds, several Aberrations with a Combined Challenge Rating of 3 or less such as Flumps or Gazers, they must all be the same exact same creature though. the monsters you summon are chosen by the DM. upon casting you must make a wisdom saving throw equal to your own spell save DC, if you succeed you take no penalty, if you fail you take 1d6 psychic damage plus your spell casting modifier and gain the following flaw: "I feel that something far away is watching me all the time." weather this is true or not is up to the DM.

The summoned monsters each take their turns after your turn obey you verbal commands (no action is required). as an Bonus action, you can dispel any amount of your summoned creatures. During each of the Summoned monsters turns, they must make a Charisma save against your spell safe DC, if the fail the remain under your control, if they succeed or if your concentration is broken, they are unable to be dispelled by you and will act on their own will for 1d10 Rounds before disappearing.
