12 4* imps to go to fully skill the forest imp. 38/50 imps acquired in about 38 energy potions. 4-6 potions each to get 25 green shells and 50 green coins. This was at a casual pace leveling up the imps to 20 with the cards from the stage, definitely doable, but definitely irritating
also sorry for not having apep or flora up all weekend, been full imp farm mode. I will be back to normal next week
I'm pretty sure the regular "full heal" skill Pinocchio and other full heal cards had to be skilled up 9 times from 20cd to 11cd which would be 54 pinos so having to strengthen and evolve doesn't matter that much especially if you have a hayyel
edit: it's also been 13 runs since posting this and no imp yet
