A finely crafted blade with a vibrant purple stone set in the hilt

You have a +1 bonus to attack and damage rolls made with this magic weapon.

Ioun Stone - Reserve. The vibrant purple stone stores spells cast into it, holding them until you use them. The stone can store up to three 3 levels worth of spells at a time. When found, it contains 1d4-1 levels of stored spells.

Any creature can cast a spell of 1st through 3rd level into the stone by touching the dagger as the spell is cast. The spell has no effect, other than to be stored in the stone. If the stone can't hold the spell, the spell is expended without effect. The level of the slot used to cast the spell determines how much space it uses.

While this dagger is in hand and attuned, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spell casting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the stone is no longer stored in it, freeing up space.

A spell can be cast as a bonus action, or a reaction, as long as the spell is normally cast at those times.

 

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
