You are very lucky sir. The best I have ever gotten in all my clue scroll's was a saradomin plate body once. I remember my bank was about 1m and then it turned into 3.4m I bought a whip and felt sooo rich.
Nice reward, I had a clue scroll in my bank and I decided to do it, was really easy level 1 I think, did it thinking I would get shit loot but I got ancient page 3 (800k)
