@grimeleven:
Oh, my mistake, thanks for letting me know. It can easily be fixed in eng_rewards.lng.
@ShadowTek:
I'm not sure what you mean by "do new things for var 4 and 5", but it's possible to do pretty much everything except adding new requirements for medals. Medals can go to any level you want. The only thing I don't know how to do, as I noted several times already, is creating new global variables, and putting them as medal requirements.
On other note, I managed to make it so that you gain bonuses as you increase your Attack/Defense.
So far the settings are set so you would get +1% to critical chance for every 5 attack and +1% to all resistances for every 5 defense.
