Adder Fang Brooch

[spavaloo]

A gild, made with an adder fang and a nugget of metal or something like that, which has the purpose of either limiting the maximum severity of Adder Bites (effectiveness depending on quality), or preventing the development of Nerve Damage, or both.

It wouldn't have an actual stat bump, so you'd be using up a valuable gild slot to get the effect.
