Part of Destiny: Nimble

Guardians are the immortal light wielding warriors appointed by the Traveler with the Protection of humanity. Guardians gain these additional features:

• Tenet of Devotion: Guardians are not limited by proficiencies, and roll Initiative using their INT rather than DEX.
• Tenet of Bravery: 1/turn, a Guardian can take a move action with a flying speed. If they end their turn airborne, they fall to the ground as normal. When hit by knockback, Guardians that haven't spent this jump can Defend and make a DEX save: on success they are shoved only 1 space away, half on fail. 20+ negates all knockback entirely.
• Tenet of Sacrifice: Guardians have innate HP regeneration. If you haven't taken ANY damage since the end of your last turn, you can use hit dice to heal (like a normal character would during a short rest).
• Tenet of Death: When reduced to 0 wounds, your Ghost can revive you at the end of your next turn with 2 wounds healed and HP equal to 1 max hit die. You can also be revived this way by an ally's help action, allowing you to not miss out on a turn. During a short rest, recover up to 2 wounds and regain ALL missing HP regardless of hit dice.
