If I remember correctly, Beggar's Cup and Troll Moss made endure elements by themselves, then when combined made Protection from Elements.
Now, both don't combine and both make a simple Potion of Endurance.
Before, they would only make an Endurance Potion if combined with Mountain Morel or Honey Lily. They still make Potions of Endurance if combined this way.
I take it this is intended? Just want to clarify.
