While I was looking for heroes that I could get another star for, I noticed that, when I was looking in the Aether shop, Marrow was not there. When I looked at his star and token page, It said that he was only available from a boss invasion (as is Solaris). That would be fine if not for the fact that Lady Nimriel, Lupina and Pontifex Mortis also have exclusivity to quest rewards, treasure rooms and pvp rewards/honor summons respectively, but are still in the aether shop. Even heroes whose tokens are not able to be gotten through dungeons, like Grog-Grog and Admiral Kreel, never mention being in the aether shop on their stars and token pages.
So, is there any way to get some clarification on the stars and token pages?
