Anyone able to recommend a good place to farm the colorless 3* Talisman EVO runes in quantity? Power Slave and Trooper Dungeon has been great for the 2* ones, but Underworld (Madness) and Brave New World (VI-X) have had really crappy drop rates (even though they're the game-recommended locations when you click on the rune). Is there a good dungeon to use instead? It's becoming a real pain to evolve all of my 4* talismans to 5* and any advice would be greatly appreciated.
