Things only Mage can achieve :D

Did you use absolutely all of them?

For example, Reha has 6 battles that must be done with AK on: Harrus, Marakash, Sarkash (in the Cave), Ziraks and Harrum (the 2 arena fights), K'Tahu.
Nameless has the following: Restless Zombie, Vlad Vegeto, White Night and Dark Mistikus. 4 more.
Elon has a ton: Uldara, Moro, Uchkuk, Shenobi, Zilgadis. In addition to those, you can find Tomas Torkve, Morto and Weed there. That's 8.

Well, maybe those may push you towards lvl 59, and maybe a bit more, but it is a matter of a little luck as well, I guess. Besides, to get to 60, even with all +XP stuff, you need to do quite a lot of suppressions of rebeling items for like 40-50k extra XP.

In any case, it's up to you to try it out. Your result is great as it is

All you mentioned except Dark Mistikus. I miscalculated the number of battles left in the game for my final AK scroll. Thought it was 5, but it was 6 (forgot that I had left Moro in Elon)

I did not pay attention earlier and my Ogre's Club rebelled just before the last XP battle once - so I suppressed it once with 50% XP boost. After that I started planning it better to make sure it did not happen again. And I did a nice job about it since it rebelled after the battle with Baal

But I did not use items that rebelled (except the Ogre's Club). I upgraded all the items I bought though - and I bought almost all of the items in the game...

I still think you need some of the tricks you applied to reach level 60.
