Battle Blessing

You perform one of several battle ceremonies. When you cast the spell, choose one of the following ceremonies, the target of which must be within 10 feet of you throughout the casting. You choose whether the blessing affects celestials or fiends.

Guiding Light. You touch one melee weapon. For the duration attacks made with that weapon have advantage against celestials or fiends.

Sleek Polish. You touch a piece of armor or an article of clothing. For the duration attacks from celestials or fiends have disadvantage targeting any creature wearing that armor or clothing.

Marking Fragrance. You touch one point on the surface (such as the earth or the floor of a building). For the duration celestials or fiends within a 10 feet circle centered on the point have disadvantage on saving throws.

If one of these ceremonies is cast on the same target 7 days in a row then the duration of the 7th casting becomes a year and a day.
