Playstyle
Bio-Arcane Barrage deals a percentage of maximum health as magic damage, so it keeps its value against exactly the targets a marksman build struggles with. Nashor's Tooth raises attack speed and ability power together, turning W into damage per second, and Deathcap with Void Staff carries the ratio through magic resist. With no dash, poke from range with the ultimate and only commit inside a fight.
