Use friends and or do solo as many people who do dung on main worlds have atleast ABA2 unlocked. Binds your best 2H and PLATEBODY (once you get SSH replace) Dung is very slow to start beleive me.
If you want decent slayer points it helps. You can speed through tasks 1-9 if you do canfis slayer master then solo 10th task on your best master. Much faster to get slayer points now.
Then is suggest making it your main new combat will definitly change pures. If you wanna make a pk account i suggest waiting till EoC is released but at the moment Quy is pretty accuracte on a pker for now
