More Marksmage Combos
Sylas S More units in passive range means more bonus damage on the main target. 
Azir S Soldiers deal 50% bonus damage — physical + magic. Damage goes through the roof. 
Yunara S Runaan's plus Q stacks Master of Duality quickly; passive deals bonus magic damage with AP scaling on crit, scaling harder every fight. 
Ekko S Ethereal Weapon + Nashor's lets one ability proc the triple-ring. 
Kayle S Kayle's ascended passive bonus fire makes autos count as two hits, so Master of Duality stacks both AD and AP at once. W heals scale massively with AP, and Kayle scales into a god — half-tank for survival. Survive long enough to ramp, then take over. 
Graves S Convert Graves's massive AP into bonus physical on-hit via Marksmage. His autos fire 4 pellets, each triggering independently — one auto = +300% AP. Late-game with Ruined King pellets become 6 for 4.5x AP scaling. Only viable when first hex is Marksmage; otherwise pure AD outperforms. Bonus damage is physical, so Black Cleaver is core late. 
Veigar S Weave autos between abilities — no more downtime. Ekko S E with crit → instant triple-ring. Long CD — pick your engage; vs shield comps, build shield-shred. Keep exploring
