Not to be too ruthless because I do really love the game but I'll walk you through my run:
"ok saving my mana against the mosquitoes for the elves was a bad idea, I got 2 healing potions from this chest last run so-"
"empty"
"ok its probably gonna be a single frog guarding this chest maybe I can hit my parlay-"
*2 mosquitoes and a frog*
"ok"
