Celstial Mote

Master's Bond. ​The Celestial Mote is intrinsically tied to its summoner's power. It uses the summoner's Proficiency Bonus in place of its own for any skill checks or saving throws. Additionally, its hit point maximum equals its normal maximum (14) or 4 times the summoner's level, whichever is higher. Its Spell Save DC matches the summoner's Spell Save DC.

Commanded Actions. ​In combat, the Mote shares its summoner's initiative count, but it takes its turn immediately after theirs. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless the summoner takes a Bonus Action on their turn to command it to take another action. That action can be one in its stat block (such as Celestial Flare, Heal, or Sparkle) or some other action. If the summoner is incapacitated, the Mote can take any action of its choice.

Innate Spellcasting. The [Celestial Mote] is an innate spellcaster. Its innate spellcasting ability is Intelligence (spell save DC uses the summoner's spell save DC, and it uses the summoner's spell attack modifier to hit with spell attacks). It can innately cast the following spells, requiring no material components: ​3/day each: Celestial Blast (see Actions), Heal (see Actions), At Will: Spark Flare(see Actions) 1/day each: detect magic, bless, sanctuary

Luminous. The Mote gives off bright light for 10 feet and dim light for another 5 feet

Celestial Blast (3/day). Ranged Spell Attack: +4 to hit, range 80 ft., one target. Hit: 4 (1d8) radiant damage. At Higher Levels. This damage increases by 1d8 when the summoner reaches 11th level (2d8)

Astral Touch (3/day). The Mote unleashes a spark of restorative starlight. One creature of the Mote's choice that it can see within 60 feet regains hit points equal to 5 (2d4) + the summoner's spellcasting ability modifier. ​At Higher Levels. This healing increases by 2d4 when the summoner reaches 5th level (4d4), 11th level (6d4), and 17th level (8d4).

Spark Flare. Melee Weapon Attack: The Mote releases a burst of radiant stardust. Each hostile creature of the Mote's choice within 5 ft of it must succeed on a Constitution saving throw (DC 14). On a failed save, a creature takes 5 (2d4) radiant damage, or half as much damage on a successful one. ​At Higher Levels. This damage increases by 2d4 when the summoner reaches 5th level (4d4), 11th level (6d4), and 17th level (8d4).

Warp Retreat. ​When the Mote is reduced to 0 hit points, it does not die. Instead, it drops to 1 hit point and instantly warps to a hiding place on its master's person (such as a satchel, backpack, or pocket). It is incapacitated and cannot emerge, join battle, or use any abilities until its master finishes a long rest.
