Guide
Day Start
Cast Aid as high a level as you can restore to increase the hit point maximum of all of your party members until long rest. Use Pearl of Power Amulet or Spellcrux Amulet to restore the expended spell slot.
Cast Longstrider on each of your party members as well to increase movement speed by 3m.
Cast Light on your weapon to always be illuminated by a light source.
Make sure you’re in Starry Form: Dragon so that you can’t roll lower than a 10 on concentration rolls until long rest.
Combat
Deal radiant damage.
If there are many enemies, cast Radiance of the Dawn and Spirit Guardians (Radiant), trying to inflict Radiating Orb on as many enemies as possible.
Use your Starry Form: Dragon bonus action, Dazzling Breath, to deal additional AoE radiant damage every turn.
Use up your Star Map: Guiding Bolt against targets you want your party to have advantage on.
If you’re holding back on spell slot usage, hitting with your Devotee’s Mace or using Sacred Flame will also inflict Radiating Orb for just an action without consuming any other resource.
Your party is now untouchable, and on the off-chance they are hit, use your Improved Warding Flare to impose disadvantage on the attack roll made.
If for some reason, you have no choice but to escape an encounter, Enhance Leap and Wild Shape: Spider can help you or a party member jump out of there.
Day End
If you still have remaining spell slots, use them up to cast Goodberry. These can be used as camp supplies.
Alternative
Starry Form: Chalice lets you use Chalice Healing as a free action upon healing with a spell. There are many other items that improve healing and spread conditions through healing that this build can make great use of.
Additional Items
- Pearl of Power Amulet or Spellcrux Amulet to restore the expended spell slot from casting Aid.
