I'm at level 7 and item durability is getting really annoying. It cost like half my gold last time I had to repair my sword, but I did it anyway. I was back to full or whatever high percentage they repair it to. Then I did a night-wraith contract... and I'm back under 50% and in need of repairs. ONE FIGHT. The buggers regenerate and its really hard to seal the deal quickly. Really fucking angry right now. It feels like I have almost no money constantly yet I buy almost nothing but occasional alchemical supplies. Maybe I'll eventually be able to cash in these foreign coins at the bank or w/e but currently this is "financial stress and irritating group combat simulator 2015".
Weapon and armour repair kits are super useful.
