Current party

• MC: Ancients Paladin 5/Swords Bard 3 - Polearm Master - Tank/Support
• Karlach: Berserker Barbarian 5/Thief Rogue 3 - GWM - Fontline DPR
• Shadowheart: Cleric 8 - Magic Initiate Druid - Support/Control
• Gale: Conjuration Wizard 8 - Control/Blaster
• Wyll: Fiend Warlock 6/Vengence Paladin 2 - SMITE
• Astarion: Thief Rogue 3/Swords Bard 5 - Sharpshooter - Ranged Ambush DPR
• Lae'zel: Eldritch Knight 8 - Tavern Brawler, Sentinel - Thrown Weapon DPR/Zone Control

Karlach's build is nuts. She's dealing 80-160 dmg per round when hasted and there just isn't much that can survive a round next to her. That said I'm considering respecing her to Wild Magic or Wildheart since I'm not using Frenzied Strike that much. She Crits so much that I've mostly been using GWM's bonus action attack and the Jump AOE thunder dmg from the maul I have her using.

Astarion's is almost as good but CBE's nerf really hurt. Though with the current stealth mechanics this build could probably solo the game.

Edit: Respeced Lae'zel and just about doubled her DPR. Also adjusted Astarion as Gloomstalker was nerfed from tabletop.
