Hydras are cool except when they get hit by enemy spells that kill them, then you lose all your fire power
Usually it would kill the CS and spare most of the other units if it were a conquest. I am not sure, it is either FS or Pop. I will have to consult an oracle.doesnt sea storm go after the units with higher FS first?
i maybe wrong though
but that purification from that hero world god removes any protective spells too,and you can them sea storm
