SSR Pride is 1% Assault per 5% health lost. So at 85% HP it's at SR Assault levels and at 70% HP it's at SSR Assault levels.
Vigor on the other hand gives the full effect at 100% HP, half effect already at ~83% HP, and ZERO damage at 50% health or below.
Vigor is far stronger than Assault, but in return, you really, really, REALLY need to be at full health at all times to make use of it."Set" increase? Pride has that from skill levels - the same amount of Assault that you get from Assault weapons. Vigor does not.That's not what makes Pride good. Lowered HP in Pride just means bonus damage, nothing more, nothing less. What you care about is that it's gives you Assault at all times.
