Mystic Genesis

Simic Combine Spell
Level 5 (?)
Casting Time: 1 Reaction
Duration: Instantaneous
Range: 60 ft (?)
Cast this spell as a reaction to a spell being cast within range. Counter this spell if it is of a Level equal to or less than 5. If the spell is countered, create a medium Ooze creature at a spot of your choice within range. This Ooze is immune to poison and acid, has a movement speed of 30, an AC of 13, and HP equal to 30. When this Ooze is hit by a melee attack from a creature within 5 ft of it, that creature takes 3 (?) Acid Damage. This Ooze has an attack that is +5 to hit and deals 2d4 Acid Damage on a success. This Ooze creature's core stats are all 10 (+0). This Ooze creature follows your telepathic orders to the best of its abilities but cannot communicate any way other than that. Additionally, it can only stay alive for 24 hours. After that, it disintegrates.
When cast at higher levels, the countered spell can be of a level higher, and the Ooze has +10 more HP for each level above 5 that this spell is cast at.
