How the numbers were obtained: Completely naked, Traits refunded, Steady weaponry.

Things to improve on: If anyone can get me the exact time taken for each skill to act, I would be able to compare time/damage/ini taken for every skill as well. This would be useful in highlighting under performing skills.
A numerical ‘steady’ value for bleed and poison would be awesome… If anyone has a good idea on how to work that out.
