I'm looking for features, spells, or items that trigger Dwarven Fortitude without the use of Ki points.
Whenever you take the Dodge action in combat, you can spend one Hit Die to heal yourself. Roll the die, add your Constitution modifier, and regain a number of hit points equal to the total (minimum of 1).
The feat requires performing the Dodge action. As such, Sword of the Paruns, Blur, Foresight, or any other thing that gives the benefits of the Dodge action would not trigger the feat, as far as I'm aware.
