For me it’s basically this :
Great Weapon Master Sentinel Sharpshooter Alert Mobile Lucky
Alert.
It’s broken. The initiative die in BG3 is a d4, which makes the bonus from alert game-breakingly good.
Yeah, i always take it for Gale ! It’s broken
Left and right feats mostly.
Everyone point at this loser who didn’t tadpole their way to flying.
Mostly just ASI, but I also get a lot of use from tavern brawler and sharpshooter. Trying a thing with spell sniper in my current run.
Polearm master is good for certain characters I feel.
Karlach zerker with polearm master and sentinel with the act 2 polearm is a beast of a character. She’ll lock down anything that comes close.
The ones you listed plus Tough and War Caster
Mage slayer mobile and alert.
I pretty much always put durable on everyone
