Lunar Link

The bearer of a Lunar Link carries with them a mark to link them to the celestial body. This can come in the form of a tattoo, birthmark, or scar.

Lunar Waning Phase: Ebb

When the moon is in its waning phase (approaching the new moon), you may use your reaction to use Moon's Guidance and redirect the damage from an attack within 30 ft. of you. Instead of reaching the original target, the damage is inflicted upon you as radiant damage. Moon's Guidance may only be used if it is night time or the moon is otherwise visible.

When a new moon occurs, your abilities climax, halving the damage you take when using your Moon's Guidance ability and giving you resistance to Bludgeoning, Slashing, and Piercing damage from non-magical sources.

Lunar Waxing Phase: Flow

When the moon is in its waxing phase (approaching the full moon), you may add an extra 1d6 radiant damage to any attack you successfully hit. This ability is only active at night or if the moon is otherwise visible.

When a full moon occurs, your abilities climax, increasing the extra damage you deal by another d6 and giving creatures disadvantage on resisting your spell effects.
