The game text on this cards reads:
Reward: Receive 4 'gold' and take this card. You must discard the "Rune of Life" and "The Well of Life" Legendary Rewards during your Experience step, if you have them.
Isn't "The Well of Life" a typo? There are no Legendary reward (LR) with that title.
My conclusion is that the card should have read "The Well of Faith", since there are no other Wells than that and no other LR with the word Life in the title besides the "Rune of Life" already mentioned.
