Many magical traditions incorporate ritual daggers into their spellcasting. You have mastered these effects and gain the following abilities

• You may use a dagger as a spellcasting focus and for a spell's somatic components.
• When you cast a spell of 1st level or higher you may make one dagger attack as a bonus action.
• You may deliver melee spell attacks by instead making an attack roll with your dagger, either melee or thrown.
• When you deal damage with a spell you may change half of its damage to magical slashing damage. You can do this a number of times equal to your proficiency bonus, recharging on a long rest.
