Commander's Strike: Melee or Ranged; when a Battle Master Fighter chooses you to attack via this maneuver. Feats: Mage Slayer: Melee; Enemy within 5 ft. of you casts a spell. Martial Adept, Riposte: Melee; Enemy misses you with melee attack, costs 1 superiority die, does benefit from a reach weapon. Polearm Master: Melee; Can make opportunity attack when an enemy enters your reach, if you're wielding glaive, halberd, pike or quarterstaff. (Per Mearls and Crawford: If the weapon has reach, you get the OA at reach.) Sentinel: Melee; Can make opportunity attack even vs. Disengage; Also can attack when enemy within 5 ft. attacks someone other than you. War Caster: Can cast a 1 action, single-target spell in place of an Opportunity Attack. Classes: Barbarian (Berserker), Lv. 14, Retaliation: Melee; When you take damage from enemy within 5 ft. Cleric (Tempest), Lv. 1, Wrath of the Storm: Not an attack, but 2d8 auto-damage (lightning or thunder), DEX save for half; When enemy within 5 ft. hits you with an attack, WIS mod times per day. Fighter (Battle Master), Lv. 3+, Riposte: Melee; Enemy misses you with melee attack, costs 1 superiority die, does benefit from a reach weapon. Monk (Shadow), Lv. 17, Opportunist: Melee; Enemy within 5 ft. is hit by an attack from someone other than you. Paladin (Vengeance), Lv. 15, Soul of Vengeance: Melee; Enemy under your Vow of Enmity makes an attack (regardless of whom it targets), does benefit from a reach weapon. Ranger (Hunter): Lv. 3, Giant Killer: Melee (Ranged works technically, but ...); Large or larger enemy within 5 ft. hits or misses you with an attack.

#6 the_move Sep 01, 2014 2:03:26	Doesn't the glaive or the pike let you do an OA if the monster is within 10 feet from you? It's a reach weapon and the OA is an attack, isn't it. So you should not get disadvantage with those, unless the monster has reach, too.

#12 Lawolf Sep 02, 2014 18:36:00	Polearm Master + War Caster works for Eldritch Blasting OAs.   OAs interrupt movement, aka they happen before their trigger. If you wield a polearm and someone attempts to enter your reach they provoke an OA. This attack occurs when the target is 6 feet away from you, as it occurs before the movement that brings them into your reach. You then blast them with up to four eldirtch blasts without any disadvantage because the enemy is not within 5 feet of you. Finally, the enemy completes their move and ends adjacent to you.

#15 Thank_Dog Sep 03, 2014 2:21:57	Not sure if anyone has realised this but with the Battlemaster's Riposte, it can be used on your turn to deliberately provoke an opportunity attack and thus get an extra attack on your turn. Pretty sweet. It's almost like the 4e fighter's Passing Attack.
#16 Plaguescarred1 Sep 20, 2014 7:52:50	Spell: Hellish Rebuke, Lv. 1: Not an attack, but 2d10 auto-damage (fire), DEX save for half; When being damaged by a creature you can see within 60 feet of you.    Action: Ready: Another way to attack with your Reaction when you can't use your action to attack on your turn is to Ready. Its not optimal being not complementary to your action, but its can still be useful.
#17 Coredump00 Sep 21, 2014 19:02:50	Just getting into 5th... what allows 4 Eldritch Blasts on an OA?

#19 2Chlorobutanal Sep 21, 2014 21:31:19	Note, however, that contrarily to what I previously thought, reach (from a reach weapon) doesn't work with War Caster, because the OA from War Caster is not being made with your reach weapon.  Therefore, in the vast majority of situations, War Caster OAs will be provoked within 5' of an enemy, and thus eldritch blast is a really bad spell to use as an OA unless you also have Crossbow Expert as a feat (to negate the disadvantage from making ranged attacks within 5' of an enemy).   Ready-Attack can be useful for Rogues affected by haste to get two Sneak Attacks, because Sneak Attack is once per turn, not once per your turn.  The rogue can attack with the haste-granted action and Ready with his or her "normal" action.  This is really only beneficial when you think you won't get an OA anyway, though, as you cannot OA and take a Readied action in the same round.
#20 mellored Jan 08, 2015 15:29:17	Command, Dissonant Whispers, Dominate, and Compulsion, and al canl make enemies provoke OA's.   Edit: and i think some fear effects too.

#22 Yunru Jan 09, 2015 0:26:34	Great Weapon Master is called "Great Weapon Master", not "Cleave With All Weapons Also Power Strike With Heavy Weapons", your point?
#23 Huntsman57 Jan 09, 2015 6:54:50	Both Parry and Riposte BM maneuvers are reactions, as are the spells Shield and Counterspell.
