This guide is simple, showing a nice build and ability order. I'll leave you some notes.

Farming:

Don't hesitate to Q a minion. It allows to get 2 minions if 2 are low on hp.

Heal a bit with your W against caster minions.(They are always in a line) This will enable easy farming as well.

NEVER use leap to farm. EVER. It doesn't do sh*t. At all. Use it to chase when you are sure you won't die, or to get away from gankers. Jump to the bushes so they can't target you for abilities.


Fighting 1v1:

Attempt to keep them isolated. That way you deal tons more damage with your Q.

When ulting, move behind them every time you stealth. That way they are more likely to miss skillshots. Take advantage of bushes too, for your passive.

Use bushes to your advantage. Once you hit them and apply their passive, lure them into the bush and strike again, then Q them. Jump to another bush and strike again and Q them again. Then, use your W to heal and attack. Ult and reposition to apply your passive again.

Team fights:
Aim for the ADC and the AP always. Coordinate with your team to use whatever cc available on them and kill them no matter what. If they flash and get away, don't chase them Attack the other carry(AP/AD) or assist your teammates.

That's all I have to say, really. Use flash for escapes or kills and ignite in the middle of the fight to damage the enemy 1v1 or as a finisher.
