Tip for the Sandworm boss

[Shyao]

If you want to have an easier time with the Sandworm boss, face the Dhorme Chimera in the desert northwest of the Library of the Ancients, where you first meet Mid. The Dhorme Chimera has a Blue Magic spell called Aqua Breath. If you use this on desert enemies, including the Sandworm, it hits them really hard. Hard enough that I had Faris, as a Ninja, use Aqua Breath on the Sandworm and she one-shot it.

For beginners, it's worthwhile to go out of your way for Blue Magic abilities. Many of them are incredible. Especially Level 5 Death.

ye blue magic is worthwhile in this game so go ahead and get most of it

Have a Thief in your party when facing Dhorm Chimera as well. Not that it has anything good to steal, but with a Thief in your party you can't be ambushed. (and Dhorme Chimera has a nasty habit of ambushing your party)

Blue magic Aqualung. Easy as hell.
