Astronomer’s Boon
This brass astrolabe has a glass back that sparkles softly when light shines through it. While looking through the glass at the night sky, the names and patterns of any constellation you can see appear alongside their stars on the astrolabe. Depending on your latitude, you may find one or more of the following constellations while looking through the glass. When you do, the astrolabe begins to glow, and you can use an action to speak the item's command word to gain the constellation's respective benefit:
The Drum. (Can be seen north of Vissau) 3 stars appear on your back in the shape of a drum. When you roll for initiative, you can expend 1 of the stars as a reaction to grant you and any other friendly creature within 10 feet of you a +1 bonus to the roll. In addition, any creature that gains this bonus to initiative can use a bonus action on its first turn of combat to take either the Dash or Disengage action.
The Knight. (Can be seen south of Vissau) 5 stars appear on your arm in the shape of a sword. When you hit with a melee attack, you can choose to expend 1 of the stars as part of the attack to cause the target to take an extra 1d4 radiant damage. Alternatively, if a friendly creature within 30 feet of you that you can see hits a target with a melee attack, you can use your reaction to expend 1 of the stars and empower the attack with light, causing the target to take an extra 1d4 radiant damage.
The Seer. (Can be seen in all of the Powder Coast) 4 stars appear on your forehead in the shape of an eye. You can use a bonus action to expend 1 of the stars and touch a creature. Once within the next 10 minutes, that creature can choose to add 1d4 to an ability check or saving throw that it makes. It can choose to roll the die before or after making the ability check or saving throw.
The stars remain until the next dusk, at which point any unused stars vanish and are lost. Once the astrolabe has granted a benefit in this way, it can't be used again until the next dusk.
