Works similar to my fighter bot so first you gotta stand on desired tile, then hit the F2 key and it should light up green/yellow. Nats I'll keep an eye on those, started near the chest btw? If not dw about it. Make sure it's the southern chest, I believe the northern ardy chest is empty and not thievable (I could be wrong).
I highly recommend doing pickpocketting all the way, it helps a lot with ban prevention. I personally view stalls and chests as "monotonous" clicking, whereas pickpocketting is inherently randomised (amplified by stuns as well). I did a lot of 99s this way, I think I only did tea stalls to 38 then master farmers to 82 and vyres to 99.
API click likes to move the mouse while clicking, I personally don't like this so I made it optional
