If you go to where Zevlor is standing here in the grove there is an exit to the left up some rocks. When you go out this exit Karlach’s spawn point is a jump down the cliff on the right. You’ll take like 90% damage if you don’t have featherfall or something similar like misty step but you get to her super early and don’t have to deal with any other combat.
I’ll do anything to get to my favorite companion early.

You don't save scum? Just me, then…
I mean, I didn't need to savescum to understand that the "paladins" were actually full of shit after talking with Karlach.
Yeah, but I can't play Baldurs gate without save scumming I'm too weak.
Don't get me wrong, I also save scum, but not in that instance.
I tend to save scum in combat because I suck, and when some course of action or dialog option has wildly unforeseen consequences.
