Could I do desert treasure? My skills are in my sig. I won't have a player blocker but I have plenty of prayer potions. Could I do it without dying? The recent quests I've done (Swan song, Rum deal and royal trouble) were easy and I kiled the bosses in them without eating or drinking (or praying for rum deal). Are the bosses in dt really that hard?

I did it at level 87. You should do it fine just use sharks and prayer pots. Also use spells on all the Bosses. Trust me if you melee/range you will be seeing alot of 0s.

Yes, just keep your prayer at top shape at all time 8-)
