On my Green toon, I used lots of minion contracts but still never got the Seiren, which is the only possible minion to use for a green toon, imho. This is the list of HeliosGreen's Minions: None of them is green. Can I get the Seiren anyway? Many other toons got it without contracts. Can I make use of them by adding to the main minion, if I get one? How to evolve minions? How to use Minium and Spinel coins?
