how to get to lvl 45 fast?

You may want to hoard some sis, feed them to Waldenbrook 1 by 1 to get him to some absurd level and kill him off (remember, mob speed is not improved by level-ups, only melee defense and offense).

Actually shopkeepers do speed up with artifacts, much like the demented ratling does. Unless you have crazy speed and powerful ball spells it isn't worth it.

i don't know about assassins, but monks are pure awesomeness.

I'm just a bit saddened that my TotRR deals less damage than AotME and now i don't know which one to use for the final dive, the trident, to maybe train one more level of polearms (lvl11, 3k more marks needed), or the Axe, that worked so wonderfully by now.

Even the old version of the axe did more damage once weapon skills were raised, since two-handed slot gives the largest damage bonuses of any, and then you have the increased criticals.
