This isnt exactly a full spark build guide, there are many of those in existance but this is a demonstration of a scaling concept that can be used to potentially beat existing versions of spark in tankiness and damage (depending on your quiver crafting) and should annihilate all versions for speed. with a very high end quiver craft you should be able to win all 3 categories
