We've just released the Crystal Tornado Shot Effect which replaces the standard effect of this skill with a swirl of purple crystals. Check out the video below or get yours here.
The new Crystal Tornado Shot works well with many microtransactions from the store. If you're looking for a neat but stylish outfit to match this effect, check out a mix of the Pitch Black Armour Set or the Gloom Armour Set with the Black Hooded Cloak and the Arc of Courage skin for your bow.
