Restrained
Functions like Grappled: you cannot move, and attacks against you have advantage. Restrained is usually caused by objects (e.g. chains, rope, roots) rather than a creature grabbing you, and it ignores Grappling size restrictions. It can end through forced movement, incapacitation, or spending an action and succeeding on a STR or DEX save, and also through logical means such as picking a lock or cutting or burning rope.
