I wish you could upgrade them for a random nymph or maybe even combine 4 relics for a random nymph...
Sorry, would never happen. The older players and people who play a lot have relics in the double digit numbers, we would get 6 of every nymph there is in just a few days.
And relic farms would clog up the t50, and everyone would have nymphs, and then nymphs are nothing special. You see my point?
