Weapon

Uncommon Requires Attunement

Versatile

Description.

The Rot Blade is a twisted weapon of decay and ruin. Its black, rusted metal is veiled in a putrid, semi-liquid necrotic miasma that clings to the air around it, briefly existing before dissolving into nothing.

Rotting Miasma.

When you hit a creature that isn't undead with this weapon, it takes an extra 1d4 necrotic damage as the miasma eats away at its body.

Concentrated Corruption.

Once per day, you can use your action to focus the miasma along the blade’s edge, channeling its full potency.
When you do, make a melee weapon attack with the Rot Blade. On a hit the attack deals an additional 4d4 necrotic damage instead of the usual 1d4.
Then the target must succeed on a DC 14 Constitution saving throw, or its hit point maximum is reduced by the necrotic damage taken for 1 hour and it can't regain hit points until the start of your next turn.
This ability has no effect on undead.
