I'm 10k/26000
I want to level quickly to 26.
Any techniques or idea how to level up quickly? Because 1 enemy I kill is only about 1 exp.
Would it help to use a 50% exp elixir? (I don't want to waste platinum, but if it helps a ton, I'll get some)

Which will get me more exp? Watcher Tomb 4? Hauntlet? Would kragg tombs give me more exp then WT4?
Please tell me.
Thank you.
