Silver Arrow
Evocation Cantrip
Casting Time: 1 action
Range: Bow range(150 ft.)
Components: V, M (a bow and an arrow)
Duration: 1 round

While aiming with your bow you pull the string back and by chanting holy words you engulf your arrow with silver flame.
As part of the action used to cast this spell, you must make a ranged attack with a bow against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects but the damage you deal is not physical, instead you deal full radiant damage
High level description: This spell's damage increases when you reach higher levels. At 5th levels the ranged attack deals an extra d6 radiant damage to the target. Damage increase by 1d6 at 11th level and 17th level.

Flamebound Symbol
3rd-level Evocation
Casting Time: 1 bonus action
Range: 30 feet
Components: V, S
Duration: 1 round

Clerics of the Silver Flame devised this spell to dispose of Karrnathi undead legions, since turning them was seldom enough.
Casting this spell is a bonus action. If you cast the spell before attempting to turn undead, your turn undead ability changes as follows: Instead of being turned or destroyed, all undead within 30 feet take 6d6 points of fire damage. A successful Con save reduces the damage by half. Undead creatures destroyed by the damage are utterly consumed in silvery fire, leaving nothing behind except their possessions.

Clothier's Closet
2nd-level Conjuration
Casting Time: 10 minutes
Range: 30 ft.
Components: V, S, M( A gem worth at least 100 gp).

When you and your companions need to attend a gale reception at the last minute, you need not despair over your clothing. When you cast clothier's closet, you conjure a 3-inch-diameter wooden rod up to 10 feet long between any two upright supports you choose. For example, you could summon the rod between two walls of a corridor or alcove. On the rod hang a number of outfits as determined by you, each of a size and type you specify while the spell is cast.

The conjured rod can hold a variety of separate outfits whose total price does not exceed 100 gp. The outfit types that you can specify include the following:

artisan's outfit (1 gp)
cleric's vestments (5 gp)
cold weather outfit (8 gp)
courtier's outfit (30 gp)
entertainer's outfit (3 gp)
explorer's outfit (10 gp)
monk's outfit (5 gp)
noble's outfit (75 gp)
scholar's outfit (5 gp)
traveler's outfit (1 gp)

The conjured clothing is normal in all respects and does not radiate magic. Even after the duration elapses and the rod and hangers disappear, the clothes remain.

Special: A character with any Mark of Hospitality dragonmark, can cast this spell without the material components, but the conjured clothes last only as long as the spell's duration.
