If we look at the skills of my morgane fairy (level 55). We can see that his skills are level 8 (so maximal). Yet if we look at the points of life she withdraws when she releases her special. They are only 544 while if the special skill is maximum level, its special should be at 672 health over 4 rounds. So that means his stage is not at the maximum level.
I leave it to the site manager to move the subject if he is not in the right place or if this topic has already been dealt with. (I do not find any trace).
Thank you for the answers.
