There's something very bugged with the preview.
I blinded Karlach to get advantage. We are on even ground.
If I aim at her body: 96% chance to hit
if I aim at her head: 80% chance to hit from the low ground, she must be a very tall woman!
Final outcome was correct: Advantage attack even though I aimed at her head.
