Nick. When you make the extra attack of the Light property, you can make it as part of the Attack action instead of as a Bonus Action. You can make this extra attack only once per turn.
Notes: Bonus: Dexterity Attacks, Finesse, Light, Thrown, Nick
This item will add extra attack bonuses to every Dex based attack made by the PC whenever it is equipped. That information is missing from the item’s description.
Also does this item do the same damage as a normal dagger? If not I can't find the damage in the description.
If it is the same damage as a regular dagger, than why should we use this one compared to a normal one?
Theoretically one would use this one because it returns to you after you throw it. But with the hidden invisible stuff added to it I wouldn’t use this one.
Not to mention that a +1 dagger that returns to you without expending a Bonus Action (so you could throw it multiple times per turn if you have more than one attack) should only be an Uncommon (Rare at most) magic item.
