Eternal Dorjes?

[Yogibear41]

I know eternal (arcane) wands exists, is there such a thing as an eternal dorje in any of the books? (aka a dorje with infinite charges but can only be used twice per day)

[Stegyre]

Not to my knowledge, but I cannot think of a good reason not to houserule them.

IMHO, eternal wands are simply a good template for any magic item that can produce a spell (or power) effect twice a day. I'd even allow it to stack: double the cost for one usable four times a day. (Why not? It's just the same as if they'd bought two eternal wands.)

Eternal Wands are created using the Wondrous Item rules (pretty much, I think there's a bit of a math difference, but they're essentially equivalent). So... yeah, they exist. They're just slightly more in the realm of DM adjudication.
