The Moon’s radiance and its position in the sky affect many aspects in the life of Faerun’s inhabitants.
Such influence can be ascribed to four major Lunar Phases:
- Full Moon
- Ascending Moon
- New Moon
- Descending Moon
In turn, Lunar Phases are split in Lunar Moments:
- Full Moon
- Ascending Moon: Waxing Gibbous, First Quarter, Waxing Crescent
- New Moon
- Descending Moon: Waning Crescent, Last Quarter, Waning Gibbous
The effects provided by these Phases or Moments are described below:
Monsters
During some Lunar Phases, monsters would roughly be more dangerous, resistant, and noxious if they are connected to the current Lunar Phase. Conversely, some monsters might be weaker during specific lunar phases. Only a thorough preemptive inspection or profound knowledge of the creature and its habits can give clues to that end.
Birthmoon
Players have the right to choose the Lunar Moment during which their characters were born, which will have some implications:
- In a game session set when the Birthmoon of a character is up, that character will benefit from a specific positive effect:
| Lunar Phase | Lunar Phase Effect |
|---|---|
| Full Moon: wealth, fertility, certainty, knowledge | Advantage on Charisma based saving throws |
| Ascending Moon: novelty, beginning, advancement | Gain temporary hit points equal to your proficiency bonus after each short or long rest |
| New Moon: rest, inactivity, destruction, preceding rebirth | Regen hit points equal to your Constitution modifier at the end of each encounter |
| Descending Moon: estrangement, purification, waning | Gain resistance to all damage types for the first round of each encounter |
