Otherworldly Overgrowth (Spell)

Otherworldly Overgrowth is a 1st level Essence spell that forces a creature to make an INT Save. If they fail, they are Restrained, and take repeated 1d4 Essence damage.
__TOC__
==Description==
You conjure strands of ethereal Essence to entangle a creature you can see within range. The target must succeed on an Intelligence saving throw or be Restrained (Condition) for the duration. 
While restrained by this spell, the creature takes 1d4 Essence damage at the start of each of its turns. 
A creature restrained by the strands can use its action to make an Intelligence check against your spell save DC, freeing itself on a success.
==Notes==
*All Essence damage dealt is doubled, but half of the damage is also dealt to the caster.
