How do you beat the ice ruins in spectrobes origins?

Well, the best way in order to defeat the boss is first, gather a lot of rice balls,then go to the boss and go all the way through the fire ruins till your in B3. Than if you want to, there's a fire symbol behind it,and it contains a shield in 1 of the stone markers.Now, go down 1 floor and incounter the boss. Try to get behind the boss and go for its tail, because he tail is its weak point. But be careful if it flips backward to face you.Once you get rid of about half of its hp, it'll turn fire version, while it was earth version before. Spika axe when its in first version, and idk what weapon to use for fire version..maybe the water type sWord. The spectrobes you should use should be that octopus spectrobe and ryza.Good luck, and remember, be careful and aim at the tail!!
