Pickle Slayer's Strike

Pickle Slayer's Strike
Magic Melee Weapon - Uncommon
If you take the Attack action on your turn and have advantage on an attack, you can forgo the advantage for that roll to make your attack exceptionally powerful. If the attack hits, it does an extra 1d8 of the weapon's damage type and the target must succeed on a DC 13 Strength saving throw or be knocked prone.
Crafted from the parts of the Pickle Monster, you can still feel its crushing advantage radiating throughout the weapon's frame.
One of the items recovered from the Magyelosaur.
