Acheron Blade

An Acheron Blade is a magical weapon described in the Explorer's Guide to Wildemount. It has not yet appeared on Critical Role.

Appearance
The blade is black arcane alloy.

Features
The sword gives a +1 bonus to attack and damage rolls. It also provides immunity to effects that turn undead.

Dark Blessing: The bearer can receive 1d4+4 temporary hit points once per day.

Disheartening Strike: Once per day, the sword can be used to, on a hit, fill a creature with unsettling dread. The target then has disadvantage on the next saving throw it makes before the end of the attacker's next turn. If the creature is immune to fear it is ineffective against it.
