Slime Bind

Simic Combine Spell
Level 2
Casting Time: Reaction
Duration: Instantaneous
Range: 40 ft (?)
Choose a creature size Large or Smaller in range. You create a harmless slime in the area they are occupying that immediately hardens, restraining them. As an action on each of their turns they may make a STR Save, breaking out of the slime on a success. After the creature breaks free of the slime, the area it occupied is still difficult terrain.
