Boss
The shopkeeper took a few shots of medicine from the team as he tested them on himself and on others to see if there are any side effects.
As soon as he realized there are none and the healing effect is indeed that good.
He even checked it against the Poison and curses and the more he tested the more the team members felt aggrieved. They are losing one shot after another for the tests when they could use it in a very perilous battle situation that could even save their life.
They didn't want to waste it.
But the shopkeeper was pretty insistent on testing it out again and again.
Some of them even steeled their hearts and dared to ask him to spare some shots. But he fumed back at them like a dragon spitting fire.
"What the hell do you guys need this for? I am testing them, aren't I? I have to check if they are all worth it before I make a business decision and if they are really worthy, do you really think I will not reward you guys enough?
