I occasionally forget whether I need to have a max level or not passive when evolving a weapon I've evolved before. For any evos not requiring max lv, no visual changes need to be made in the Grimoire. But for those that do. There should be some small but visible text above the passive/s that says "MAX LV" in the Grimoire with the same colour and style as the text in the Grimoire for the evos requiring it.

yeah i think a little M near the passives would be cool
