thats not much, Dmg Items and Atk speed Items make him shine, then his 400% more dmg is up around 1500-1675 tahts combined with his Atk Speed.
I usually go all dmg items (theres like 3 total that or good)
what I can remember:
-both gloves (2 items)
-dmg output of 55 (artifact) (1 item)
-speed scroll (gets him to ~14.6 speed when used) (1 side item)
-walk speed boots (1 item)
-life gain artifact (1 side Item)
-best artifact ingame (1 Item)
-lightning ring for atk speed (plus, a plague spewing, lighting atk is funny-wierd) (1 iem)
thats 6 items and 2 side items, last side slot can vary
on that level, let them push to where the giants get stuck and kill a tower, then end it...
