Towards the end of Tumbbad (2018), Vinayak Rao ties multiple dough dolls to himself so as to lure the Hastars, so that Pandurang can get out of the Womb safely. It is also shown that initially the multiple embodiments of Hastar (each for a doll) who fight each other over the dough dolls.
My question:
Why couldn't they toss a single doll at a time, let the Hastars fight over it and "kill" each other, and do this until all of them are "dead" and then get out safely?
