First off, thanks for that - and all the advice. Been playing since early March and am dumb about numbers in general, but always delighted to learn.
This is my setup having changed to:
Magma will helm +6 (lvl 41)
Wild talisman of will +6
Archon fatality +6 (lvl 41)

... and the same with lvl 41 magma will +6.
