Notes[]
May be stacked with  Sure Footed for complete immunity to knockdown

Can be stacked with  Fast Deflection to provide a total of +190% shield recharge rate.
Shield recharge modifiers affect the rate at which you gain shields, but Fortitude does not shorten the delay between taking damage and initiating the recharge.
Trivia[]
Fortitude was added in Update 9.
This mod used to share its icon with  Vigor, another Nightmare Mode mod.
In Update 13.0 (2014-04-09) Vigor got its own icon.
