Tormentor's Flail (Patreon)

Weapon (flail), rare

The head of this flail is in the shape of a metal skull that's pierced with large construction spikes. When you hit a creature that's missing any of its hit points with this magic weapon, the creature takes an extra 1d6 psychic damage.

In addition, when you roll a 20 on an attack roll made with this weapon against a creature, that creature must succeed on a DC 15 Wisdom saving throw or be frightened of you until the end of your next turn.

A broken body may still yet resist with a strong enough mind.

A broken mind with a strong body is a threat that feels no pain.

But a broken body and mind, together, leaves only true surrender.

Torment—true torment—leaves no room for resistance.
