This is going to be a short description about this build.

Key points

Ancient Spear is your bread and butter initiator and fury generator. With reduced cd and the dot you can afford to use it to get a quick boost of fury. I cant tell you how many times I imitate with it, follow up with a spear during the team fight, and then get a clutch spear for a kill on a fleeing hero.

WOTB is you ult of choice, with the increased skill damage and basic skill damage Sonya pretty much turns into more of an assassin than a warrior. You can afford to pop this before every team fight and then ancient spear in then right into some SS.

Dust Devils now the main reason you are going to take this over life funnel is for the extra damage its going to give your WW. I am a firm believer that my WW will be interrupted before the channeling finishes. So with that in mind when I use my WW I want to put out as much damage as I can with it before it gets canceled.

Nerves of steal and ignore pain, these are pretty self explanatory your are going to pop them when you initiate so you can soak up all the damage.

Your main damage source is still going to be SS with WOTB on you are going to still deal 500 damage close to end game per slam.

If you jump into a pile with a few heros around you I usually start with WW because of the AOE damage.

I will also note that Sonya cant do it alone, and in most cases I will not engage in a one on one fight because you will probably get wrecked. Especially if the hero has some kind of interrupt because then you wont even be able to WW to heal. If you have a partner in crime Sonya is great because of her high damage and she is tankyer because she is classified as a warrior.
