Yes, a non-member can go to the Wilderness, encounter a revenant, and get himself killed.
It would be any high level revenants. Located in the wild
Yes, it is both Non-Members and Members.
I don't think there are. Only Elvarg, which can only be fought once during the quest. If you try to get into the room he's in after the quest, you just simply can't go into the room (answer doesn't include revenants, which can be found in the wilderness).
yes, but only one and that's Elvarg from dragon slayer other than that nope
Get some resource (for example, do some mining, or kill cows), then sell it at the Grand Exchange.
No.
you cant
Al Kahrid in non members.
Yes.
No, the sawmill is a members only option.
what the heck do u mean? non members can mine runeessence! and non members cant mine any kind of essence in runescape isn't even a quistion idiot. :(
For non-members there is only one place: high north in the Wilderness, level 46 or so. It is a dangerous place, mainly due to the Revenants. Also, there is lots of competition. I estimate that you can get about the same amount of profit, per hour, as mining clay (which requires mining level 1).
