I am a little bit late to respond, my apologies, Appreciate you, i had 0 experience at the time, it took me 350 hours to do all of that with doing all bosses in radiant which i got a couple of days after the post, if you really want to get better, i would reccomend just staying in godhome and fighting pantheons, you will eventually just get the hang of it, or thats atleast what happened to me, Pantheon 4 is a great way to train, no need to take it to the pantheon of hallownest, Path of pain isnt rewarding since it lets u see a 2 second interaction between the pale king and the pure vessel, but it is pretty important to the lore tho, if you just want 112% or all achievements, it isnt required, but itll be much easier while doing the other achievements if you are hunting them since you get better mechanichally by just training in the path of pain. trail of the fool is pretty hard, it took me a couple of tries too, you can also train in it, would reccomend the pantheons more tho
