Example - Panzer Dragon passive increase recovery by x1.5, and it's working on passive skills like autoheal each turn - Holy Priestess heals for 5605 each turn under this buff. (x1.5 increase from her 3736 normal heal)
But active skills like Heal III remains unaffected, Holy Priestess skill recover 6920 (same as without x1.5 recovery buff) instead of 10380.
This looks just like Grim Reaper recovery bug, but this time other recovery buff skill.
