thank you for the answers. i tied the black pearl rings and still only did 2 crits. now working on getting the following build all +1 gear where possible and double melded with int, loresman or mp/enmity -

Felt hat of Intelligence
Felt Bliaud
Gridanian square shield
Vanya sash
Boarskin ringbands of storms
Woolen tights
Spruce pattens
Mages choker
Mages Earrings
Zircon bracelets
Zircon rings

This gives me the following stats Magic accuracy 451 and int 353

now my choice is electrum scepter with double int (acc 468 +31 from buttons, int 385)

or

lightning brand with 1*int and 1* magic accuracy (ac 467 +31 from buttons, int 369) potency +20 and lightning potency +10

Does anyone know which would do more damage?

thank you
