Exploration is tricky...

Before I start, if you're going to use profanity in your username or comments, don't bother commenting. I'll report you.. Exploration has a total of 20 energy, and 1 energy refills every 4 hours.. Stage 5 gives 3 enemies in 16 hours, so that's 3 energy.. Since you need to clear up to Stage 4 to get energy, it's 1 enemy per 1 energy.. But I'm not a machine, I can't check every 16 hours.. If I put 2 enemies in Stage 4 for 2 energy.. It seems like a reasonable structure to refill 4 and then clear stage 5.. Checking Stage 4 with 1 enemy frequently is also a hassle.. If I put 2 enemies in Stage 4 and the energy depletes too quickly, It's complicated with Stage 4 having only 1 enemy.. I could just stick to Stage 5 and occasionally do Stage 3 fully, which would require 6 energy, but that would need 6 pets.. It's complicated..
