Will [Foot of the Mountain] lower the drop rate of [Peak of the Mountain]?

Hello everyone, I try to farm a 3lp Peak of the Mountain in dungeon, and it often drop Foot of the Mountain without the helmet in T4. The database said the drop rate for helmet and boots are 50% and 45% in T4, and the 45% for helmet without any other gear in T1. So should I farm T1? Or the drop rate is independent for each gear in Lightless Arbor? thank you

Pretty sure the drop rate is individual for each item. Only saying this because I got the foot and the peak at the same time

Yeah, and I forget that T1 area level is only 20, so got to farm T4 to get 3lp no matter what. Thanks buddy!
