    Really wondering if Repelling Blast, War Caster, and Sentinel (or Polearm Master) allow opponents movement to be halted and pushed back with an Opportunity Action? I had read the posts, but cannot find the full 3 piece combination clarified. It seems to allow this as it can use a reaction, allows for the Spell instead of melee, and triggers from 5′-10′ depending on 3rd option (feats: Sentinel or Polemaster) Great for 1 on 1 but, but mobs will render Warlock a bit heavy, if he starts acting invulnerable. Am I correct in this?

      Because here is the proposed order that seems to allow it. Warlock (12th) or Human Warlock (8th) has the following. Repelling Blast invocation. Polearm Mastery (and is wielding a Quarterstaff), War Caster, & Sentinel.

      So if a creature enters 5′ of you, he triggers an AoO (PM), so using the Qstaff still in your hand(s) WAR CASTER (allowing for wielding, and casting) grants AoO due to creature’s movement that triggered AoO (thru PM) may use REACTION (1/end) to cast spell. (EB w Repelling Blast invocation, if hits successful pushing creature 30 -40 feat. SENTINEL allows AoO if hostile creature within 5′ leaves your reach, even with disengage action. Thereby triggering SENTINEL (when hit a creature w/ AoO, creature’s movement and becomes 0 (zero) ) While this can, depending on actually hitting the target, Force back and STOP their movement for the round, it seems logical and unless in a bottle neck doesn’t seem OP. As missile attacks, AoE attacks, mob rushes, etc.. cannot be stopped. So I am thinking of allowing it as I cannot see a rule infraction, and I like the player’s ingenuity of the tactic. (Once again confirming what I have often said, RPGers tend to be incredible problem solvers and have higher IQ’s and I happily look forward to finding them for employment.
