DotaCinema's Guide to Weaver

Introduction

Hey guys, welcome to my guide! I'd just like to throw a shout out to DotACinema for giving me this guide. Their video is below. :)

Please note, however, that all of the written part of the guide is actually written by me, and not just a copy. Only the skill build/item builds are from DotACinema.

Summary [Pros/Cons]

Weaver (In my opinion at least) is an excellent carry that's a lot different from the other standard carries you see a lot in DotA 2. (And DotA 1 for the most part!) Although most carries are generally easy to kill if focused, Weaver offers a lot of survivability through his skillset, while still being able to put out tons of damage.

Pros:

Good Survivability/Escaping
Great Harass
Amazing Late-Game Damage

Extremely Item Dependent
Not much damage in late game
Can be zoned out in lanes against other ranged heroes
