Can’t answer first question.
My least favorite enemies are:
1. Demonic Wizpig
Fought him more than 15 times and lost all of the battles. His attack is very powerful and he summons ghost allies to heal himself. Used 37 potions and 23 Veggie Cakes and still failed. Spent 30 Lucky Coins on reviving. I could only defeat him with Mighty Eagle.
2. Banshee
I hate this guy so much he summons a lot of ghost allies and since they’re ghosts they revive so you have to kill them at the same time.
3. Monty
He doesn’t attack but his summoning is annoying. One turn and he summons 2 rogues.
He has high health and gives his allies a defense boost (25% attack boost)
4. Ice Shaman
Steals any received healing by the target onto the pig with the lowest health. So annoying. His healing heals for a lot, and it’s not a heal that waits 2 or 3 turns.
5. Witch Doctor
Reduces received healing on a bird by 100% and it lasts 3 turns.
6. Shaman
Reduces received healing by 50% on all birds. His heal cleanses.
