How useful is in the long term?

Would anyone recommend paying for experience to level up an extra level?

Are the weapons useful?

Would the money be better used later in the game, such as in the battle tower?

Is the well still here after the broken valey is corrupted?

Thank you.

after the valley is corrupted i dont think you can go back, the item i got was OK nothing special but exp is always useful especially at the start of the game.

I myself take the accessories that come with +1 wisdom, which I use till almost end of the game. Couple with the quest amulet that came with +2 wisdom, you can +3 wisdom for free.

When I finish the game, my level is just slightly reach 35, even with 5k exp extra, it wont able reach 36, so judge it by yourself

Anyone know where all the wishing wells are since I hear she states there are others, I missed out on the 1st one myself by the enchanter, didnt know about it till after the valley is poisoned.

There is only one wishing well accessible in D2:ED. There was another in Divine Divinity, but if it still exists after the war with the Black Ring that transformed some of the landscape, you can not get to it.
