The number one reason I made this build was because I felt like the traditional (static shiv, phantom dancer) builds are lacking a lot of what Shaco really needs. The biggest reason I don't like the normal builds is because I feel like crit hit on Shaco is a loosing battle. At the end of most of all the other builds, you have like 35% crit chance. My main focuses on this build are Life Steal (combo with spirit visage, and good sustain), CRD, MR-because it seems like shaco gets bursted down Really easy in team fights, and health.
The spells may seem a little strange on Shaco. But I cant tell you how many kills I got because of Exhaust. Its not only a good combo with you're Two Shiv Poison, but its good For reducing the enemy's attack speed and damage in 1v1 fights Or 1v2 fights if your ult is up. But too tell you the truth, I really don't think Shaco even needs Smite. You could get flash and exhaust too.
