Topple

Weapon mastery property. Requires a feature that unlocks this weapon’s mastery; weapon proficiency alone is not enough.

Trigger and saving throw

When you hit a creature using this weapon, you can force it to make a Constitution saving throw. On a failed save, it has the Prone condition.

Topple save DC = 8 + your Proficiency Bonus + the ability modifier used for the attack roll.

For example, Proficiency Bonus +3 and attack ability modifier +4 give DC 15. Use the attack’s actual ability modifier, not automatically Strength or your spell save DC.

Limits and Prone

Topple does not itself state a creature size limit, require dealing damage, or impose a once-per-turn limit. Applicable immunity or a more specific rule can still matter. Each qualifying hit can offer another save.

A successful save prevents Topple from imposing Prone. A failed save does not prescribe a one-round duration: the creature follows Prone’s rules for standing, movement, and attacks. Topple itself does not deal extra damage.

Example weapons: Battleaxe, Maul, and Quarterstaff.
