Short Sword with Thundering
The sword has the Thundering ability which adds an additional 1d8 of electricity damage when a critical hit is struck. This damage is not multiplied. The target must then pass a DC 14 Fortitude save to prevent from being deafened.
This was the sword used by the Arisen Grettir the strong to slay the dragon Nidhogg and has since been passed down from generation to generation. As legend has it, Grettir struck blows with such force that any solid blow would ring out with a thunderclap. Electricity courses through the blade, providing a painful shock to those it cuts. However, the electrical element can be used to produce a tazer-like effect, stunning and subduing those struck with the flat of the blade.
