Oh, I thought I posted the answer to this. Guess I didn't.
HP = 100+(Candies_Eaten^0.4)*2.1
Where can I get invulnerability potions?
Mix 2000 candies x number of potions you want.
So if you wanted 10 potions, mix 20000 candies.
Mix the forget out of them, aka, till it's no longer showing a number. (60 seconds)
Also, how many gmooh potions are required to spam before i find the cow?
It's a 1/4 chance of going there, so in a perfect world, 4, but there's always the chance of getting it your first try, and not getting it even after trying 100 times.
good god the castle enterance is impossible
nvm guys use berserk potions
Nah, you just need boots, and more health.
nothing happens to my lollipop production after I got the horn from the Cow King :c
It wont show it on your lp/s, but if you look at your actual lollipop count, it should be going up 3x as fast.
I think all hard mode does is restrict you to 100 HP.
