Hello there,
Did you guys notice how funny this reward is?
For upgrading 20 pieces of armor to refinement lvl 7, we get 3 medium runes.
We have 20 pieces of armor in total and from lvl 7 we use advanced runes...
So we basically get only 20000 coins and few extra coins for selling runes. As it cannot be used in spacetime shop either.

Could you update handbook reward to advanced runes or allow us to at least get chips for mediums? :) thanks
