Note: I got no cam to backup these reports but if someone provide me with a virus free tibicam NG for 7.6 I will get proof and re-cam it to host on youtube.
Henkespally
1. Always shoot bolt a split second before he hit SD.
This is impossible without bot since attack delay is slower than SD and if you have SD on crosshair then release SD and right click atk right after the bolt will come a split second after and never before the SD.
2. Hit every SD single SD.
Not really a proof but seeing as he has no skill at all in other parts of tibia its weird.
Deathis
1. Can hit SD under roof.
2. Hit every single SD in open.
Same as for Henkespally, this is not impossible without bot but if he has played tibia long enought to hit every SD in open he should be skilled in other parts of tibia aswell.
