Superior Leather Armor's text refers to it being a heavy armor.

[Soothsilver]

The treasure card Superior Leather Armor has the text:
 
"Banish this card to reduce all damage dealt to you to 0; if proficient with heavy armors, bury it instead."

 

It should be "light armors" instead. The card has the light armor keyword.

 

I never actually played the card, I don't know what its actual effect is.

Thanks a bunch!
