On my first Gith playthrough I convinced her with a nat 20, which was awesome.
On my next two Gith play throughs she didn't make it off the beach. Her armor is a great early upgrade even if it looks hideous on anyone not her.
Also, she is an incredibly easy fight. Like... My Gith Muscle Wizard one shot her with a longsword. My Gith dual wielder ranger took her out on the second round without being hit once.
Not a great performance for someone who was just going on about how she'd kill me seconds ago.
Her health is surprisingly low for a Cleric.
Isn't it like 9 or something?
