Champion idea: Hextech master

I have not put in any base DMG numbers in because i have no idea what they could be. Actives for each ability can also be changed (but i want them to have synergy with the corresponding HEXTECH item, not like Xayah and Rakan, but more like Morgana and Jhin, who have no listed synergy but a very good combo
