I defeated Astaroth in Diablo 4 on the first try. Pretty easily, in fact. On Veteran tier.
I think I’ve finally gotten my Barbarian really rolling. Only level 35 (34 while fighting Astaroth) so still not in endgame gear. But I’m relying less and less on healing potions. In fact, healing potions are now more of an “oh shit what the fuck hit me” situation.
