Another problem is my fq with +13 skill (12 from upgrade and +1 from equipment evolve) has skill level 12 on the battle. You can confirm it on the provided battle link. I am well aware of bug that affects all heroes to have skill decreased by 1 level on the battle. but in my case only hero affect on this party set up is fq. My main has +2 skill of dark meditation although it is with out any equipment.
