When we finished BG2:ToB, our demigod-like characters were chunking giants and casting Time Stop, Wish and Meteor Storm.

Fighting as a low-level character in BG3, brings back memories of those ol' BG1 days. Goodberry spamming because those 1HP heals really made a difference and trying to use any advantage you can think of, like pre-emptive buff spells before a difficult fight (really, who goes into an innocent-looking room casting aid, bless, stoneskin, mirror image, contingency, protection from magic/petrification... without some hindsight of a reloaded save? :p)
