I have a Green Cat Thug (dropped by the boss in Tomb of the Beguiler, maybe?) that gives its eponymous card at Ancient.
I do not play Pet Derby.
I'm trying to figure out whether there's any point in continuing to train this pet to Epic. Will it get me anything more than what I got at Ancient? I've consulted the "Guide" and have read far too many threads here in the forum, and still have no idea.
I train a pet to ancient and if they have 2 traits that only boosts their own stats, i do not continue. I know the probability of them getting a useful trait is probably higher, but i feel i could work on another pet with the possibility of gaining 3 or 4 useful traits, not just 2. If your pet has useful traits, then by all means train him to epic.
