Well.... I look at the same kined of gear you look at most of the time but depinding on your lvl you can buy one thing like for example a robe and it can have health,mana,and strangth. i know that becase most of my freind's are life and we allways talk to each other and try to fined the best deals all throuout the spiral.So really i try to fined stuff that can give me more health and mana and strangth.It's hard but it pay's off in the long run.
It kinda depends on what you want. If you want a lot of health then get health multipliers on everything. Or if you want to strengthen your attacks then get attack multipliers and so on. Right now on my Theugist I have +128 health and +5% power pip on my hat, +9% life attack and +14% life defense, on my coat, +3% power pip and +3% life attack and + 6% life defense on my boots, my wand gives me +1 pip at start, my athame gives me +130 health and + 98 mana, my ring gives me +6% power pip +8% outgoing heal. So it just really depends on what you want to do.
I play a very supportive role, my family and I travel throughout the spiral together and they constantly need mending so I don't do much offensive work. I think I'll take a look into HP and Pip gear, goodness knows I never have enough pips!
