I won't list items that are specific only to one class because I don't consider those "best."
Best items in-game:
- Fungi tunic (duh so overpowered on a twink of all types of classes)
- Manastone (can be used effeciently on several classes)
- Rod of Annihilation (extremely well item you can put on any caster to help them level up faster - especially necro and enchanters)
- RBG - great stats, all/all, good haste
- pre-nerf fungi staff - another really great twink tool and powerful item
- puppet strings - powerful in the right hands
- dragon tooth - 49 pet, can be used to level you up (if you have the ballz to use it lol)
- locket of escape - bind your melee/tank
- Amulet of Necropotence - any class can use, cool skele effect, changes faction
- Pre-Nerf guise of deceiver - read above, except cool dark elf illusion instead of skele
those are some i can think of that i would consider the best...like i said i wont put anything that is targeted for just one class, those wont be the best
