Overview

This build focuses on high burst damage with an invisibility engage & great kill securing executes.

Items

1. Mind Razor

This item is a must build for the first slot, Giving you your mana & wave clear for the whole game.
I recommend only building your soul chalice. then jumping immediately into item number two VANQUISHER after completion of VANQUISHER then complete MINDRAZOR

2. Vanquisher

I recommend Vanq second, as this will allow you to start securing kills in early game teamfights. This Item only gets stronger as the game goes on and healthpools increase, it becomes a fantastic execute.

3. Omen

This is a fantastic item number 3 as it combos amazingly with item 4 ENVY Boosting the damage of your first basic attack, and having that basic attack become a guaranteed Crit because of ENVY'S effect. Not only will the first basic do insane Dmg but it will also reduce cooldowns by 2 seconds allowing your invis to come online again much faster to combo again sooner.

4. Envy

This item is the bread and butter of the my preferred playstyle. Upon basic attacking an enemy while invis. the bonus dmg from OMEN will become a guaranteed Crit for huge Dmg. then the following combo Q -> RMB -> RMB you'll be dealing 10% bonus dmg. Killing any squishy almost instantly.

5. Perforator

This item is simply here for its great statline, and 30% Pen. Also the passive 10% slow paired with the slow you get from the Q will achieve a total slow of 45% making you're RMB much easier to hit.

Playstyle

This specific build focuses on an extremely high burst Dmg combo after exiting invisibility.
The gameplay loop is as follows
1. go invis and safely get within basic attack range of opponent
2. Basic attack enemy taking advantage of the OMEN + ENVY Combo
3. Follow up immediately with the Q -> RMB -> BASIC -> RMB Combo
4. Finish kill if safe.
5. Finally use invis again and re-position
6. Rinse and repeat

Notes

Use Ult to pull back fleeing Opponents or to peel for yourself / your carry
Use your crest ORTUS ANY time you're going to secure a kill. Alternatively if you need to run away. The invis + ortus combo can get you out of most sticky situations
Finally in teamfights try to take off-angles, and play like a ranged assassin.
