As a free player, I feel the  rewards (e.g. 4 star daemons) are too hard to get. You get 1 "completion" each time you get 6 Enigma Gems. On average (from my personal experience), you get 1 Enigma Gem per 15hp spent. So it costs around 6X15=90hp per set of 6 gems. I am a free, potionless player, so this will take too long.

For a free player like myself, I feel this event should be treated as a tug along. Advance your main story normally and just get whatever rewards you can get. Try to get at least Halberd .
