I found this video to be a good summary of the epic Endurance (purple) cards in The Elder Scrolls Legends (includes all sets until Houses of Morrowind). It is good to watch if you are new to the game and trying to build your card collection and need to think about what epic cards to craft (=get).
The video is from Warrior7’s YouTube channel featuring himself, Karakondzhul and EndoZoa.
According to the discussion, the Top 5 epic Endurance cards are:
- Shadowfen Priest
- Disciple of Namira
- Corrupted Shade
- Iliac Sorcerer
- Necromancer’s Amulet
