Offlane. Burrowstrike is like a short blink that can also stun, which is great for all sorts of shenanigans. Caustic Finale makes creeps killed after they've been autoattacked by you explode, which can be great against melee laners if you force them to lane around their creeps. Sandstorm creates a lingering damage AOE and you are invisible when inside it, the enemy will need to buy dust or wards to see you so exploit this. Epicenter need to be channeled completely for it to work, hold down R until it completely and then stay as close as possible to enemy heroes. Burrowstrike combos into Epicenter.
