My big issue
 

Don't get me wrong I love this game but the system in it, in my opinion, needs to be changed. The biggest sting to me is Runes. If you have level 4 runes that you spend a week earning it can literally be destroyed by the RNG of the system. Whoever has the best rng wins every fight.
"But you can get a book that gives you better chances"
A book to get better chances, Wow it doesn't guarantee crap I'll tell you that.
I was given 250,000 gralats in delteria to level up runes the best runes I ended up with was Level 3 and yes I used books. I went up to upgrading to a level 5 but it broke.
(sandz gave me the money to help test out the system before it went into beta)

My suggestion- Get a book that guarantees runes to not break when being upgraded.

RNG- Random Number Generator

If i did this it would be a Gem Shop Item

Bad suggestion imo.
There should always be a possible loss of runes so there’s an itemsink and more of an incentive for people to go out and collect them. They’re tradeable aswell so people losing them keeps their value up.
I do think it’d be acceptable if you keep more runes if you fail in general or through the use of books as long as you’d still lose atleast 1 no matter what

There is 2 Books one that prevents lost of runes and one that raises the percent.

UMm
 

I think now the runes should stay the way they are :\
