Several inconsistencies here:
Expanded Sigils refers to "coat of arms" while Expanded Colors states "Coat of Arms" (Capital C and A). Both the item and the tooltip.
Expanded Crests refers to "coat or arms" (same as above, but also "or" instead of "of"?) Both the item and the tooltip.
I know, it's minor... or perhaps that is what you want it to be...
Gaming since the womb... no, seriously; at least 35 years.
Thanks for catching that.
