Just a tool to map out Perks.

Tells you the Skill level required for each skill and character level required for # of taken perks as well as having the correct data on all levels of the stats (I had seen the sword mastery incorrectly labeled as +10/20/30 on 1 site... it's 10/15/20 crit bonus)

You can copy the address bar and paste it to share your builds too.
