team up mission question

kingrobert

When you do a team up mission, afterwards you are given an opportunty to buy the hero at a discount. How much is the discount? I don't want to do the team up mission until I have enough glu coins to buy the hero but I don't know how many it takes.

The normal set for heroes that cost 400 credits get discounted to 340 once u do the mission. So im guessing its like a 10~15 percent discount on credits for every hero
