Sentinel does not grant an opportunity attack.
How many Opportunity attacks do you get per turn?
A character can take any number of opportunity actions per round, but no more than one opportunity action during each other combatant’s turn. A character cannot take opportunity actions, including opportunity attacks, during the character’s own turn. Some creatures have an ability called threatening reach.
Does Sentinel beat mobile?
Sentinel does not beat mobile or fancy footwork. Sentinel beats disengage.
What’s the difference between opportunity attack and Sentinel feat?
Here’s why: the feat doesn’t specify the bonus attack’s timing, and when a reaction has no timing specified, the reaction occurs after its trigger finishes (DMG, 252). In contrast, an opportunity attack specifically takes place before its trigger finishes—that is, right before the target creature leaves your reach (PH, 195).
What happens if you do not have the Sentinel feat?
The targeted entity does not have the Sentinel feat. It does not matter what caused the creature to make this attack in the first place so you can use Sentinel. It is important to note, however, that this attack granted by Sentinel using your reaction is not considered an Opportunity Attack.
What are the conditions for triggering a Sentinel?
The only conditions for triggering Sentinel are: The creature is within 5 feet of you. The creature makes an attack agains a target that isn’t you. The targeted entity does not have the Sentinel feat. It does not matter what caused the creature to make this attack in the first place so you can use Sentinel.
Who is a good candidate for the Sentinel feat?
Fighters, similarly, while they can have awesome AC, tend to have relatively low single-attack damage and enjoy high DPR from multiple attacks. Barbarians are pretty good candidates for Sentinel, because of their resistance to damage, but struggle to impose much threat for that one attack, despite Rage.
