You can attempt to grab another creature provided you are within Reach and have at least 1 arm free (or some other way to grab them). On a failed STR or DEX save (DC 10+STR or DEX), a target:
- your size or smaller, is Grappled.
- larger than you, you gain the Riding condition.
Forced movement (pushing a grappler away), incapacitation, or spending an action and succeeding on a STR or DEX save can end it.
Restrained Functions like Grappled, but is caused by objects (e.g., chains, rope, roots) and ignores size restrictions. It can also be ended through any logical means, such as picking a lock or cutting/burning rope.
