One question I do have,
I take it that the defensive equipment for both is roughly the same?

Apart from that I have noticed that in hero's relm at least defensive equipment (after a certain point) doesn't seem to make a difference unless you BLOCK.
So you just need to kill them faster than they kill you. OR dodge/block lots... which is hard as they seem to have 110+ hit for all the bosses (as well as 100+ in Resilience and Break)

but no/very little defenses...
So think of them almost only having a sword/staff and a spirit ball only and they still have all those POWER points....
