Melee Crowd Controller

You are accustomed / have acquired the skills to handle multiple foes within melee range with suitable weapons you're proficient in. You gain the following benefits:

• Increase your Strength, Dexterity, or Constitution score by 1, to a maximum of 20.
• You gain +1 AC when engaged in combat with 2 foes within range / reach of your melee weapon, +2 AC with 3 foes, +3 with 4 or more foes.
• You have 2 additional reactions for only Opportunity Attacks each turn. This is on top of the usual 1 reaction per turn, which can also be another Opportunity Attack.
• Roundhouse Attack - as a bonus action, you may attempt to attack everything around you within range / reach of your melee weapon.
  • You must be proficient with the melee weapon used.
  • You only make 1 attack roll, that applies against each individual creature's AC (allies included) within melee range / reach.
  • Damage dealt to all creatures hit is as per one normal off-hand attack: weapon damage die roll + any other applicable bonuses, without any ability modifiers.
  • Normal (off-hand) critical hit and damage rules apply.
  • For each creature hit this way (attack roll > AC), that creature can then roll a Dexterity saving throw, against the same attack roll (Dexterity saving roll > attack roll), to receive only half the damage.
  • Allies that are hit make their Dexterity saving throw with advantage. Abilities, feats, or class features like a Rogue (level 7), Monk (level 7), or Ranger/Hunter's (level 15) Evasion apply to this Dexterity saving throw.
