How to play as Vel'Koz
Once Zed can all-in with R, hold E for his return and place it just behind yourself to catch him. Use Q and W to farm or poke while E is held.
Stay behind minions when Zed uses WEQ so his shurikens lose damage through the wave; don''t give him the full combo before committing to a trade.
After Death Mark(R)''s initial dash, Zed reappears behind his target; a well-timed Tectonic Disruption(E) can knock him up before he follows through with more damage.
