To start level up stats because iron branches suck and drow is as thin as paper,then put two levels into the frost arrows so no one can escape you pro mlg strats, level up stats again and max the arrows first, ultimate at the normal levels of 6 11 16.
at level 8 get 1 level of silence and then just do whatever suits you best, the skill build that i have put here is my choice of preference.
How to Drow like an mlg FaZe ranger
When you get the first level of frost arrows start spamming the enemies in your lane, and 360 frost-scope the enemies like the MLG player you are
try unleashing that OG beast inside you while you silence the other team like a boss
when you get the shadow blade start hunting noobs by doing exactly this super pro MLG af combo "q w q q q q q q q q q q q q" and they will mostly die
