So what level will I finish the first Act as? I'm at level 4 now and feel like I've done so much, even though I don't have Karlach, Gale, or Halsin in my party yet.

Finally bought Baldur's Gate 3 for 20% off and started playing it. I'm enjoying it so far. Playing as a hunky bard who will impregnate Shadowheart soon. Wish me luck.
