This thread was made especially to those who are finding a hard time making killer type skill builds, or getting bored of the good old type killer builds ( E.G. Fury swipes, chemical rage, grow, hunter in the night, etc.)
Here, I'll give you some of my skill builds in which I've used over the years.
Please be noted that some of the skills that I will mention will not work / stack in the older versions of LoD-DotA
(E.G. 6.74 v4c and lower.)
Skill Build #1 : Counter Skiller (If you're having problems with skiller type enemies.
Mana Burn
Frostmourne
Phantom Strike
Rage (if STR) / Essence Shift (if AGI)
Omnislash / Culling Blade / Mana Break ( for finishing blow)
Shadow Dance ( for sneak) / Grow (for damage)
