Predecessor Builds > Zarus > Shinbi Counterbuild

A lot of people don't build right to counter Shinbi and end up being outdamaged by her. This build gives you a little bit of magic resist for the early game and lets you chase her down to melt her healthbar.

Last two options are situational, but I usually pick Draconum for a bit of physical resist for teamfights and Tainted Blade for the damage boost and anti-heal.
