This is my first hero guide so appologies if it isnt great. I will add a threat level indicator when I figure out how.

Playing this build i find that there is enough burst potential to focus down any lone hero from full health however tanks like Stitches and Anuburak can be dangerous because of their silly health regen and chasing ability which can ruin your escapes. Squishy champs on their own are basically free kills. Beware of Nova and her Tripple Tap.

These talents are geared towards a late game playstyle so you may feel a little underpowered at low levels.

Other Talent picks if you dont like the ones i have suggested could be:
-Rapid Displaceent over Seasoned Marksman. Personally I dont mind the farm needed for Seasoned marksman and i find it pays in the late game but some people may find the blink cooldown too good to miss so this one is on you.

-Vampiric Assault could be used instead of Empowered Attacks if you feel like it, you will however notice a difference in your attacks' effectiveness.

You may notice that if you activate Searing Attacks then attack from stealth, that by level 20 your first basic attack will deal most of your opponents health. That is very much the point of this build. Only ever blink out of combat and never in as this leaves you lacking an escape for 10 seconds which IS enough time for you to die and always try to blink over walls if possible as this makes you far harder to follow. Never go in against more than 2 people and never go in against 2 people unless one is a low damage support. With this build you should be able to sneak up on one enemy who is a part of a group, burst them down and blink out, then rinse and repeat. In this mannor it is possible to kill large groups of heroes solo unless they are so close together that they are basically hugging in which case you will get murdered.

I hope this helps guys.
