I'm trying to get the hang of shaco too.
Theres so many options now:
- I like going boots of Mobility, but others could work in some cases.
- Blade of the Ruined king + Wit's end is a great combo
- Sheen is great, can build into Trinity force then get infinite edge
- Go Tanky with new ice fist item which is tankier version of Sheen, plus Wit's end or something with life.
Important to always position yourself behind your target as shaco
I've been using some wierd combo of offensive/defensive masteries, really not sure about that.
