Incoming Math! We’re making a change to the diminishing return formula in 1.0.8 The end result is about identical returns for masteries up to about 50, but it drops off just a little after that point… for example at mastery level 100, it is about 5% lower. We’ve found that exceedingly high level players are getting just a few more mana surges than we would like. If you think of a diminishing return formula as: CHANCE = (LIMIT \* MASTERY) / (MASTERY + DECAY) We currently have LIMIT = 1 & DECAY = 100 We’re going to change to LIMIT = 0.73 & DECAY = 62 When we graph the differences in the mana surge chance we get the following ![](https://us1.discourse-cdn.com/flex019/uploads/gemsofwar/original/2X/0/0efd78dc1daa55b8677ea344d052ee386c358831.jpg) That’s a fairly small change… if you have masteries around the 150 mark, then every 10 matches would give you 5 surges instead of 6. --- _[View the full topic](https://community.gemsofwar.com/t/1-0-8-preview-part-2-upgrading-troops/1832)._
