Hi, there are something like 6 propacks availaible....each gives certain % bonus if i buy all will they stack the bonuses??!
Farm quests until you get enough nobs to buy them. It'll take you a lot of time, but you'll save the money.
Yes the bonus will add up, and if you buy all the pro packs you will end up with a total of this : Attack - 30% Attack defense 25.5% Spy attack - 31% Attack defense 29% Basically adding percentage to your stats. Although i don't recommend spending the $$ on pro packs, hunt quests as stated.
For future reference, dillybar has a thread under the questions/feedback section of the forums where you can ask questions like this and get answers without having to make a thread. It's pretty useful to use Good luck and happy KaWing!
