Calvin's plan was ballsy indeed, for it involved luring the tiger out of the mountain.
The Witches from the Sabbath were monsters that the three couldn't possibly hope to defeat unless they fought them one by one. Fighting these Witches separately was basically impossible for when Witches were in a Sabbath. They were often inseparable. Of course, there were some exceptions like how Old Lady Cynthia walked away from her sisters.
But Calvin and the three couldn't possibly bank on a game of chances.
They must be certain and there must be no unaccounted variables whatsoever in the upcoming scheme that they were about to unfold.
The fried Corpse Eater Flesh gave three vials of Corpse Eater Oils. Calvin had one, while the remaining two vials were given to Ricardo. At first, Ricardo wanted to refuse, but he was eventually convinced by Calvin to take the two vials since Heisenberg had the ability to cover his fists with the divinity of the Goddess.
