Eclipse are 10-floor special events that implement a special rule, which limits players to Demons from certain races, and yield various rewards. The rule restriction changes, while the rewards refresh, on a monthly basis.

Tips

These stages are designed to be clearable with a full roster of fully-leveled demons that are evolved to 4★ or already naturally 4★. You can easily clear the lower stages without such demons though!

Brands make a big difference; make sure to make good use of them! Even low level brands with the right attributes (i.e. Magic Attack% on a magical attacker) and the set bonuses can make all the difference.

Try to clear up to Stage 9 for the 4★ ticket. Training demons to do Stage 10 isn't generally worth it, unless you already have the demon of that race ready for it.

Make use of the Dx2 Leaders! Especially Chalk Eater and Templar Dragon can be useful, as these give you more press turns or make items spammable respectively.

Near the end of the month an Event will be held that makes Eclipse Stages cost 0 Stamina. This can be a good opportunity to clear it, if you have not done so.

Also make use of the free 4★ Demon you get at the end of the month before. It is usually a good way to easily clear the early stages, even without other leveled demons of the chosen Race(s).
