M'aiq knows in most alterantive universes when a homunculus dies it loses something; experience and/or intimacy.
M'aiq knows not why this is not the case in the lands heRO.
Anyway, M'aiq thinks, if you feel sorry for your homunculus, you should also feel sorry for your potion bottle you want to throw at it. After all if you lose that you will never be able to use it again, nor ressurect it.
