There are a few things that i find truly frustrating about the game (having to watch a slow animation for ten minutes on every item i upgrade comes to mind). But once you hit level 20 on the keeps it really is a good drop rate, you dont need 'thousands of energy' if hitting keep level 20.

I understand the frustration but would focus on building a team that can do level 20 of the keep.

I  hated  grinding  potions  at  level  15,  once  20  was  released  it is  a  whole  new  ballgame.

I'm not sure if I remember it correctly, but didn't you (horsemen) even pull a Teela and made a complaining thread in the forum how bad she is? (Maybe it was another user, not 100% sure.)

Perfect champ for stage 20 teams in spirit and magic keep.

with 1 million downloads of this game each month I look forward to the next horeman next month for a laugh

To add insult to injury, today I had the mission 5 sup pots from lvl13+ magic keep, did 20 multies on lvl 13 and got 9 of the things, 3 stacks of 3.

When your luck is in RNG is kind to you, when your luck sucks, go find something else to play for a few days.
