Slark is a semi-carry roaming ganker that excels in single target assassination and just generally annoying the hell out of the enemy team.

A few things to take note of :

1. Slark is very fluid you have to learn how to play him through trial and error.
2. Dark pact then pounce, or pounce wait a tick & dark pact to remove a predictable reactionary stun or debuff.
3. At level 6 you need to be roaming and ganking.
4. This guide merely represents how I play Slark and have done well. Think of this guide as a compilation of various suggestions and not strict rules. You could very well see something I have missed or not seen
