The deities hesitated.
They could actually increase the level of strength their armies had access to, and this was basically what the Life God was suggesting.
But, if imparting godly strength to mortals was so easy, it would only be a matter of simply bestowing divine boons to all their fanatic believers and forming an invincible divine army boasting millions.
There were certain clauses and factors in place limiting and restricting bestowment, the most important factor being that it inadvertently depended on the deity's influence on Citar. For every mass bestowment, there would be a subtle hint of alienation from the planet that could only be offset by the deities' territorial authority.
Of course, this was not really that much of a problem to some of the bigshot deities that held majority of the faith and territory on Citar.
