What's this site?
http://bloodlinecalculator.com/ was born from an idea of a player of Bloodline Champions.
His goal was (and also will be) to create a usefull tool available for free to all the community, mainly for give to every player of this game a way to show and to compare his/her favourite build of traits and gems (without being forced to take tons of screenshots and to upload them on internet) but also with the future plan (near future) of collect all community preferences about build for specifics bloodlines or roles and to publish them, aiming to show to new players which traits and gems will more often face in their career as well as giving to veterans a place where quickly find the most common builds for the bloodline they're looking at.
