When a Minion starts to grow, you may cancel the process by clicking the 'X' icon on the top-right corner of the "growth" mini-screen afterwards, the Minion will attempt to grow every time it levels up.Minions grow from 0 to 2 times depending on the species. Certain Minions also become more powerful through Growth at a certain level, as well as getting a different sprite.(There is another sort of glitch after Lv.60: the Minion keeps gaining Exp until its Exp bar is full inoffensive as well).( Note: Upon reaching Lv.59, you won't see your Minion receive Exp anymore in battle don't worry, though, it's just a glitch, and you'll know that the Minion has reached Lv.60 when the Menu indicates that its last skill point is to be spent).
After receiving sufficient Experience, Minions will grow through level up: they recieve an increase in their statistics, making them more powerful.Both winning or losing a fight will provide Experience to all your Minions, including the fallen forfeiting however gives no reward. Minions earn Experience throught fighting.and Fourthly, two specimens of a given Minion can a posteriori differ in their stats by their Stat Affinity: a bonus of +5% in one stat, randomly assigned to the Minion when you first acquire it.
The base values for these stats are Minion-specific, meaning that several specimens of the same Minion would always have the same stats at a given Level, a priori. Speed: the factor defining the Minion's priority for making a move in the turn, related to other allies and foes (priority proportional to Speed stat, sorted in descending order).Healing: the amount of damage the Mininon can heal from its allies/ or: the amount of extra Health it can shield its allies with.
