As a bonus action, a weapon you touch sheds radiant light. For the duration, the weapon radiates bright light in a 3-meter radius and dim light for an additional 3 meters and deals an extra 1d4 radiant damage when it hits, or an extra 2d4 radiant damage against undead and oozes.
If the attack misses by 4 or less, the weapon deals half as much damage.
Alternatively, you can touch a quiver containing arrows or bolts, granting the ammunition pulled from it the same effect. The spell’s magic ends on a piece of ammunition when it hits or misses.
You can increase the damage by 1d4 for each additional mana or psi expended and an additional 1d4 for every other additional mana or psi expended.
Crusader’s Mantle. You can expend 1 additional mana or psi to radiate holy power in an aura shaped as a sphere twice as big as normal centered on you, awakening boldness in friendly creatures. The duration changes to 1 minute/mana, concentration and until the spell ends, the aura moves with you. While in the aura, each nonhostile creature in the aura (including you) deals the extra radiant damage when it hits with a weapon attack.
