Swords Of Judgement

You summon three swords of pure light behind you, then you can give them one of two commands:

Restrain: The target of the swords must make an DEX saving throw (DC 18 + Wis) and if the target fails he is restrained for 5 rounds and is dealt 4d4 damage.
Slay: The swords fly to the target and pierce the target, he takes 10d8 damage on a failed save or half as much on a succesfull one (DC 18+Wis).

When used against fiends or undead, they receive double damage and are restrained for 2 more rounds

May you use the power given by thee to your own discretion, bringing justice to this world

When casted at higher levels the target is restrained by 1 more round or they are dealt +2d8 damage per spell level
