Gotta love a series that sets rules then breaks them immediately. He has 1 hp. He takes a fall from 20 feet. World book says that does d10-1 damage. He survives, because it rolled a 1-1 and he got lucky apparently. Mind you, thats not the actual fall damage dice from dnd, the author is only using dnd as a basis when it’s convenient. Later — Goblin shoves him from standing to face in the dirt. No damage mentioned at all. He survives. Seriously, way to set the tone for your horribly written plot armor manga.
