Sentinel 5e feats

In Sentinel 5e feat dnd, you must master methods to benefit from every drop in any enemy’s guard, gaining the following benefits. When you hit a monster with an opportunity attack, the creature’s speed matches 0 for the rest from the turn. Monsters stimulate opportunity attacks of you even if they get the Disengage drive before leaving your reach.

Suppose a monster within 5 feet of you attacks a target other than you (the target doesn’t have this feat). In that case, you can use your reaction to earn a melee weapon strike against the attacking creature.

You can attack with a melee weapon with the Attack action, but it is not the Attack action itself. Suppose you produce an Extra Attack. Then the 5e Attack action enables you to attack twice – two melee strikes but only one Attack action. Source of Sentinel 5e: Player’s Handbook.

Is a character with the Sentinel 5e feats unbeatable in a duel?

The Sentinel 5e ability against Disengage (PHB 192) says the following. “Monsters provoke opportunity attacks of you even if they get the 5e Disengage to act before leaving your reach.” It does not help with creatures ten feet away from accessing your reach or transferring from ten feet to five feet as they are not “leaving your reach.”

Therefore a character with the Sentinel 5e feats is not unbeatable in a duel.

For this to work, it requires:

You to strike with the opportunity attack every time.

The antagonist to have no reach or ranged choices available. There to be only one opponent because you only get one reaction.

It presumes that the contestant has no choices or will not use the options they have. A disengage action enables them to get close. A grapple halts you from moving away, for example. A miscreant can turn after turn with their 5e Cunning Action (PHB 96); other classes have varying techniques.
