2 Bracer 1 fairy fire you can bait with low hp and high dying light burn damage when you low hp.

On offlane harass them with W (lvl.2 fire spirit) and finish them with Q+W (lvl 4 or 5). When got 6lvl. Tower is not a problem. W W W Q W R and get the kill.
Buy urn for regen and damage. When urn is 0 if u kill urn get 2 charge so u can 1 heal and 1 damage. Veil shiva is the 1 man army item. Use shiva than dive to them Veil + W W W W + R if they try to atack you, you will got rampage...
For escape E + D + tp
F.A.Q
Why icarus dive is not 1 lvl ,sunray 1 lvl on lvl 4 so you can faster max sunray?
-Because lvl 1 sunray sucks. you can do more damage with auto atack and you have more mobility and W spam hit walk hit walk w hit walk. Until level 8 this build (2q4w1e1r) is more powerfull than 1q4w2e1r and u got the early game more easily :D
