I’ve been debating this. I’m looking at the classic sets (mage). I’d say this one and maybe the bird are worth investing into. If you don’t have a 110, use your plat to level up fast by buying maxx cave tickets and the all access elixir. Once you reach 105, cap your character in the event. The event is the best way to make quick gold at the moment. Opening up birthday boxes with plat is another one, but I don’t recommend it. Opened 100+ and still haven’t gotten anything that’s worth 7m+. Farming the event has made me at least 200m so far. But you gotta grind hard these next 4 days. Some days I don’t even get drops as well.
