You gain a (+2) bonus to attack rolls and damage rolls made with this magic dagger. It otherwise uses the normal dagger statistics.

Once on each of your turns when you hit a creature with an attack using this dagger, you can deal an extra 2d6 poison damage. If the target is poisoned or has taken acid damage since the end of your previous turn, you regain hit points equal to the poison damage dealt by this property. This healing cannot raise you above your hit point maximum.

The dagger can hold up to 3 doses of poison applied to it. You can apply a dose of poison to the dagger as a Bonus Action instead of taking an action. Applying poison this way does not alter that poison's normal duration, saving throw, or other rules.
