I'm 100 Combat and I had a problem with the final fight. I went through about 13-15 sharks on the first form, after that I only used about another 5 more, but it was still difficult. Even if Jagex didnt have the combat requirement on there, anyone below 85 wouldn't be able to do it. (I'm suprised if most people under 95-100 don't have a problem with it) I know of a level 126 who died during the dreamland fight, so this quest is just hard combat wise. There are some quests geared towards skills, this one is just geared towards combat.
