One minute.
That is how long a summoned [Chimera's] life is supposed to be worth. This is the exact duration used up by these creatures which summoned at both Allesiah and Sylph's location. However, there is one unique factor connected to the duration once a [Chimera] has been successfully created.
If there are excess materials, corpses fitting the initial requirement, lying around then these can be used as extenders. The duration of a [Summoned Chimera's] existence gets prolonged, using up the materials found near them.
And, unlike the startup requirement, the maintaining amount of sacrifices is considerably lower. Hence, with number of deaths Zeke has already caused, the [Chimeras] have 30 minutes at best in order to fight with the human.
