Amulet of the Devout and Moon Sickle not working

These items do not increase a Spell Casters DC when equipped and attuned. The + to hit bonus is being calculated in, but not the DC bonus.

Is it something we are doing or is it not in the system to do this?

It really messes with immersion and makes us take a moment as we remember to take it into consideration ourselves.

I think you might want to take this over to Foundry’s discord to chat about, it doesn’t seem like a forge issue by itself - Foundry VTT
