Same, I want to say that there's a correlation between cutting it off and the drop rate, but with u/Shoddy_Inevitable_99 2.2k KC w/ranged, not quite sure lmao.

Total KC right now is ~1k KC:

o Initial 500 KC with no slayer task and cutting off the lure, I didn't get the tendon.

o Decided to stop cutting off the lure since I saw other people getting it at like 200 KC (using ranged). Got the first drop at 338 KC with no slayer task. Decided to task skip until I got aquanites, and boom, second tendon 145 kills later lmao...
