Hexblade...Reach Weapon...Polearm Master...Level 5 2nd attack...Armor of Agathys...Mirror Image = tanky melee goodness
4 attacks at level 5:
2 main + 1 "but-end of the Reach Weapon attack" + one reaction attack
10' reach...so hit and back up and wait for the advance to trigger the reaction.
BTW this worked for my barbarian with mods in BG3.
Wounded and retreating...the only one left standing...out pops an invisible Githyanki Captain for the ambush kill...my reaction triggered and she was dead (I had beat her down pretty good before hand).
The Hexblade mod in BG3 is great if it is patch ready. you can also use the Devil's Sight / Darkness combo to gain advantage and whomp enemies good. I used a Great sword with Great Weapon Fighting in the first play-through (limited to level 4).
Having Wyll to help cast extra Darkness spells made controlling the battlefield pretty easy. Advantage is powerful! If they implement Elvin Accuracy then you are a crit fisher.
