Okay, I bought the Sentinels pack now - and finally a Shared Bank ! Yay !

I'm not sure about the rest yet … I'm going to sleep early this Friday, I think that I'll be online for a longer time on Saturday evening/night.

My Wizard just died trying to find out more about the Bargain Bazaar, by the way. He didn't have enough health potions, no hireling available, and nothing summoned. And when he was dead I found out that he had a BB running. When was that ???
So I decided to finish the Lighthouse quest which I hadn't done on elite difficulty with him yet. 1500 experience points - not bad for that quest. And this time WITH a hireling !
