Notes

• The Moonbeam is considered a summoned entity, separate from the caster. This has the following implications:
  • Casting Moonbeam or  Move Moonbeam does not break  Sanctuary, even if damage is successfully dealt.
  •  Radiant Retort targets the beam itself, leaving the caster unharmed; as the Moonbeam does not actually have hit points, it will not be damaged either.
• Since Patch 6, casting Moonbeam on a blighted area in the Shadow-Cursed Lands leads to the caster losing Concentration over the spell and dispelling it, but damage is still done.
•  Move Moonbeam is a "granted" spell. Granted spells are issued to the caster after casting the original, and can be recast without spending another spell slot as long as  Concentration is not broken. Granted spells such as this are not directly tied to the casters' repertoire of known spells (i.e., their spellbook icon in the game). Therefore, if a granted spell is cast when multiclassing, subsequent recasts (in this case,  Move Moonbeam) use the spellcasting modifier of the most recently acquired spellcasting class rather than the spellcasting modifier that was used for the initial casting of Moonbeam. In this case, it may result in an unexpectedly low spell save DC.
• The incantation for Moonbeam is Ex Textura, Latin for "From the weave".

Bugs

• Despite being an Evocation spell, Moonbeam does not interact with  Sculpt Spells.
