I think a full set of iron that gives 'low' protection is fine with a newbium weapon. But let's be honest, with no buffers, you can get to 10 or 12 combat in a matter of minutes for some people. And, because you're gaining as much exp as you are, as quickly as you are, money won't be that plentiful at lower levels. Just something to consider if slightly better armour would be available in Loth. 500mcgrail for 10 pieces is still 5000mcgrail.
