Sentinel
Complete guide to the Sentinel feat in D&D 5e. Lock down enemies, protect allies, and control the battlefield with devastating opportunity attacks.
Benefit
You can stop enemies in their tracks with opportunity attacks, punish foes who ignore you, and protect allies from harm.
Mechanics
Sentinel provides three powerful defensive and control benefits: **Opportunity Attack Stops Movement:** When you hit a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn. This stops any movement they had remaining. **Attack Creatures Who Attack Allies:** When a creature within 5 feet of you makes an attack against a target other than you (and that target doesn't have this feat), you can use your reaction to make a melee weapon attack against the attacking creature. **Ignore Disengage:** Creatures provoke opportunity attacks from you even if they take the Disengage action before leaving your reach. **Important Details:** - Reducing speed to 0 stops movement from all sources (including flying) - You can only use your reaction once per round - The ally protection feature triggers on the attack, not when the ally is hit - Works with reach weapons for 10-foot control zones - Disengage immunity makes you extremely dangerous to flee from
