Hey, i just learned that some mounts and other things in the crown shop are also available for gold. But not all and i thought that it would be a great idea for certain elixirs like energy to be bought with gold. especially since there is a double pet XP even going on wizards will run out of energy fast. Sometimes wizards don't have crowns so it could really help them.
Yes. I'm not sure on all the maps that award them, I get them regularly in Tanglewood Way and Helephant Tower in Wysteria and all levels of Avalon. Yes I know those maps cost crowns, but they are one time purchase. Takes less than a week to get the free trivia crowns enough to buy each map.
