This tip was given to me after a while, so it might be better to share it so new players get to know sooner. Some basic info:
- Legendary doesn't drop.
- Epic only drops in Events.
- Medium drops with 2 stars (2 stars when summoned through ticket idol and 3 stars when summoned through diamond idol).
- Common drops whenever they feel like (when they come with 0 (zero) DOTs, you can reroll for a chance of having them quickstart with even 2 DOTs, but mind your resources)
This way, you don't have to play the full Event Quest again just to try your luck. You can actually 'guarantee' your drop in every play and save Energy for other uses.That's that. Just mind you that in some battles, the Epic creature will appear in the 2nd of 4 waves, which makes it easier to stop the game if there was no drop. But when the Epic creature is in the LAST wave, be quick or the game will read that the battle ended and you'll lose the timing to try another drop!
