If I remember correctly gorillas on ape atoll with dharoks, super sets, and using prayers was only like 50k-60k/hour.
Since we don’t have that I think the best place to train would be Taverly on the poison Spiders.
-prayer altar is there until next update.
-spiders are aggressive
-no wasting time on drops
Really the only way to get max XP is to utilize those 4 things. Using super attack/strength. Using prayers. Always being in combat( aggressive NPCs), and not picking up drops.
Otherwise I’d just give Moss Giants a go with super sets no prayer and not picking up drops/burying bones. They have same defence as deadly red spiders (30) but more HP.
Poison Spiders have 60 defence so even with prayers you might not hit as often so could be less XP.
