Blessing of the Sword Dance

You invoke the blessing of Eilistraee to bestow special
properties to a bladed weapon, such as a long sword or
greatsword. You plant the sword’s blade point-down into the
ground and then perform a special dance known as the Sword
Dance, briefly brushing each of your limbs against the sharp
edge of the blade to let your blood onto it. At the completion
of the spell’s casting, the weapon gains the following properties
until the spell ends.
● The weapon itself is immune to acid, radiant, and thunder
damage, as well as rusting effects.
● The weapon can be treated as a holy symbol by worshippers
of Eilistraee.
● The wielder of the weapon has resistance to thunder
damage and advantage on saving throws that would apply the
deafened condition.
● The weapon glows with a silvery radiance when drawn,
producing bright light out to 10 feet, and dim light another 10
feet outward. Invisibility is suppressed in this light.
● The weapon is treated as a magical weapon for the purpose
of overcoming damage resistance and immunity against nonmagical
bludgeoning. piercing, and slashing damage.
At Higher Levels. If you expend a spell slot with a higher
level than 3rd for this spell, then you double the duration of
the spell’s effect for each level above 3rd.
