More often called by their nickname "screamswords," the Nexian sealing blades were developed by the Arclords of Nex as special tools to ward off Gebbite infiltrators and assassins. Screamswords are +2 greater striking disrupting silver longswords with a couple of extra tricks. Each Nexian sealing blade can sense undead within 60 feet and responds by screaming loudly until there are no longer undead within that range. This same screaming can be unleashed as a sonic blast if needed.

Activate interact

Frequency once per day

Effect the screamsword does what it does best and lets out an ear-shattering shriek. Each creature in a 30-foot cone takes 10d6 sonic damage (DC 31 basic Fortitude save). Any creature who fails is Deafened for 1 round, or 1 hour on a critical failure
