Champion's Mantle — Lunar Crusader's Mantle (2024 PHB, Upcastable to 9th)

Champion's Mantle reimagines Crusader's Mantle with a lunar theme and full compatibility with the 2024 Player's Handbook spell mechanics. The spell is upcastable to ninth level and offered in multiple main versions so you can tailor cost, damage type, and duration to your preferred balance. Main sets are grouped by action cost: one group uses an Action Point, the other a Bonus Action Point. Damage profiles include alternating cold and radiant dice by spell level, cold-only, or radiant-only variants. At spell level 1 the aura grants allies an extra 1d4 cold on weapon attacks and unarmed strikes, with bonus dice increasing in an alternating pattern as the spell is upcast. Sub-versions control concentration and persistence: some require concentration, others last 10 turns, persist until a long rest, or are permanent. Only one main version should be active at a time. An optional All Caster Addon adds the spell to all shared level 3 spell lists. The mod has been tested in large mod collections and may merge with the Cleric shared level 3 list; manual installation with a BG3 mod manager is recommended.
