How to Utilize Mind Blast and Cloak of Shadow Ok, I am a level 41 flashdancer, this is my first diablo 2 char ever, im a noob. Any ways the skills I use are Dragon Talon, Lightning sentry, Death Sentry, Fade, and Shadow Master. But I keep hearing how cloak of shadows and mind blast are important skills. In hell soloing diablo, which I am doing until I get a decent set of armor, I am doing fine using only the above listed skills and not even coming close to dieing. However in nightmare and hell mode I think I am going to have to start using mind blast and cloak of shadows. The problem is, I don't understand how those skills work. And how to use them. Can someone please explain? Also, where are the best places to find topaz? In hell I'm only finding saphires and diamonds. FURTHERMORE, if I equip an act 1 merc with a crossbow that has 41%MF, will that MF% work if the merc is shooting? Or does MF% only work for the actual char using it.
