1. Figure out the unique things each type of demon does, as well as what makes each type happy. You can ask people in game, but you're an evil conjurer so other evil conjurers might not be terribly forthcoming.

2. Find sources of a/s/b. I know some types of devils will cast barrier on you, but if you're going to use demons then you'll want to find your own source. This is sort of standard mage advice.

3. Find ways to haste yourself and your servitors. I can think of at least two. This isn't as important with devils, but hasting your demon and elemental will increase your offense a LOT.

4. Find convenient ways to slow yourself. There are two that come to mind. This isn't absolutely essential, but it sure seems like it'd make your life a lot less tedious.

5. Read the help files for all the conjurer edges, then play your character in such a way that imms will want to reward you. Some of the conjie ones seem pretty nice. Again, this sort of applies to any class, but certain of the conjurer one seem extra-useful.

6. If you plan on using night gaunts as an *initial* attack, or even if you don't, you'll want to do some exploring to find nifty areas/rooms to gaunt people to. I haven't played an evil conjurer, but I keep thinking about doing it just to test whether some potential gaunt locations I've found would actually "work".

7. Bone up on your scion studies, and hope something interesting starts happening leader-wise with that cabal, because that (and Tribunal) are the only real optionss for you. (Sorry Herald!)
