Does anyone know when/how to use this card? It creates additional dice with some symbol but I can't see any option to use nor roll it. I asked this question on CDPRed forum but I haven't got an answer...

"Once per roll, you may spend 1 ♦ on this card.."

Notice that the value in the bottom right of your card is 0, meaning you already used up your charges.

The added screenshot was only for reading as there is no such characters to type the "eye" sign here. :D

I know how to charge cards and I charged this one many times, used it during battle - it adds a die with "eye" sign on it, just like on Triss's hero die. The problem is that I'm yet to find any use for this "eye" sign while playing Yarpen, the dwarf. :(

Beside Triss' special rolls, you can use this "Eye" in blue investigation cards, e.g in card Occultists.

I think there is at least one more card (or monster) that use "Eye" symbol, although I agree that's too little.

At the moment I am doing test run (solo game) - in turn number 26 I found card named Occultists.
And yes, it requires an "eye" die! BUT the problem is it requires TWO of them! :D

As I can use Dwarven Amulet only ONCE per roll/encounter and produce only ONE such "eye" die (I've tested this) this card still has no use for me as one "eye" die = STILL fail. :)

Still looking for other such cards....

I've finished my solo play after over 60 turns - no other such card appeared.

The mystery of this card still exists - any new ideas what it is for?

My guess is that it was supposed to be in Triss' deck. That is the only place it would have a use if I am not mistaken.

Maybe? ...but hasn't Triss got her own amulet as a card? That, and also: the card name has "dwarven" word in it, so I suppose it was planned to be in Yarpen's deck.

After nearly a month (sigh) I've got official confirmation that this card is useless in beta - it will have some uses in full game.
