Venomous Strike

You prepare to enchant your weapon in preparation for when you hit a target and release the spell. The next time you hit a creature with a weapon attack during the spell's duration, the weapon drips with toxins, and the attack deals an extra 1d8 poison damage to the target. Additionally, the target must make a Constitution saving throw or be poisoned until the spell ends. As an action, the creature can end the effect on itself with a successful Constitution check against your spell save DC.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for every slot level above 1st.
