Quests/Tasks/Third Party Assistance (Bad Title)

I use rswiki for some calcs (for flipping and the odd ones they have their) + all things I'm curious about (skills and their training methods, items etc), but for quest and usually calculating what I need for certain levels I use tip it, mostly because it has been around forever and I'm a lot more familiar with the site then other sites.

Zybez I use just for the jad task, but that's about it.

I agree with what others have said though, I'll do what I can in a quest without using a guide, the biggest reason I look at a guide is simply to get the items that I'll need for it before I start, having to go back and get items when you're in the middle of nowhere is never fun and since it doesn't really ruin any of the puzzles or storyline, I'm fine with checking guides for that reason only.

Rarely will I look at a guide to help me with a puzzle, but it happens sometimes (mourners quest 2 and I one of the elemental workshop quests, can't remember which one it was)
