I'm fairly sure you can get experience in every skill while dungouneering, but for many the experience earned is extremely lowered such as rune crafting.
I got 97-99 attack from 1-80 dungeonnerng, wich was arround 1.6m
also 60k prayer xp (70-71)
few runecrafting, crafting and constructions level.. they were under 40.
And 50k magic xp
At lvl 80s no prayer I was getting about 15-20k combat xp an hour. It's pretty decent xp considering it's not even the primary stat that you're botting. Also all the other skill xp is really nice as well
You CAN expect summoning and prayer XP in dungeoneering If you botted 1-120 you'd have about 70+ in all skills that doors require. Unless you play legit and leech of world 61 as a skiller.
Some people go into c2 dungeons and just use up all the resources and enter a new dungeon. Since skilling was made faster in dungeoneering, you can actually get decent xp/hr down there. If you use c2 you're guaranteed that the dungeon will be easy and that there will still be resource spots.
