I just got katze, and have his skill icons! I don't know how to edit them in, though, so i'll leave them here?
The Emperor Upright - Recurring Anthem (http://game-a1.granbluefantasy.jp/assets_en/img_mid/sp/ui/icon/status/x64/status_6439.png). Applies to all allies when Katze joins the frontline.
First Movement: Bide - Refrain of Biding (http://game-a1.granbluefantasy.jp/assets_en/img_mid/sp/ui/icon/status/x64/status_6437.png) Applies to Katzelia on skill use, but affects the rest of the party.
Third Movement: Guard - Refrain of the Guardian (http://game-a1.granbluefantasy.jp/assets_en/img_mid/sp/ui/icon/status/x64/status_6442.png) Applies to a character of choice on skill use, does the effects already listed on the page.
All of these buffs are undispellable! Let me know if there's a place where i'm supposed to put this stuff.
