Summary

The idea of this build is to farm and sustain a lane early game. This build is recommended for solo top on 3v3 or mid on 5v5.

Early-Game

The method of play here is to 'turtle'.
1.Don't over-extend when there is 'mia' (especially when there is a jungler as MID will be the main focus *1v2*).

2.You may be more aggressive after you get some more spell vamp, so after taking some damage just pop your 'W' on the next fresh minion wave to heal up.

3.Try not to spam your 'Q' skill shots early game, you run out of mana fast, just farm and sustain the lane and use your 'Q' when ganking, being ganked, or helping with a gank.

Mid-Game/Late-Game

The method of play here is to 'gank and help in team fights'.
1.Try to always stick around allies, even if they do get on your nerves and attempt to "ks" all your hard work a assist still gets you gold (which is way better then death).

2.Play defensively until a fight is started by someone other then you, unless you have no other choice (e.g. a tank).

3.When a large team fight occurs, using your ultimate close to all your enemies early rather then later to get kills helps A LOT for both you and your team mates giving moral to your team mates due to the stun and damage (making your allies less likely to flee/lose the team fight).
