When duration of Ava ends and Calico recasts Ava, DMG amp scales up to 30-32%. It seems to not affect Calico's real damage as the buff is brought back to 20% upon leaving Ava.
Additionally, it would be nice if time required to gain Damage Amp was included in the description of the ability, as shown in an attached image.
