Ah Mipedians, Perim's very own lizard boys. Believe it or not, a generic mugic's flavor text describes Mipedians in the game. "Strike first, strike fast, strike hard, strike last," -
Prelude to Dominance. Come on, how doesn't that sound exactly like the Mipedians?
The corner stone that Mipedians has been built on is invisibility. They get the jump on their opponents and try to finish them as fast as they can, much like an ambush. That is one reason why there is such a low amount of Mipedians with high energy. It is because they never had to rely on energy, because their battles are usually over so fast that it wouldn't matter how much energy they have.
Now how about some mugic staples of the Mipedians?
Melody of Mirage, and
Song of Shelter come to mind. If you think about it, overworld is good at solving problems, underworld is good at causing problems and Mipedians are good at preventing the problems from ever happening. Mipedians have some of the best defensive mugic there is, I know I always dread it when I see a Melody of Mirage being played on one of my attacks!

Now on to warbeasts! Warbeasts are a very odd thing to talk about, because they don't really fit into the Mipedian stereotype. They don't turn invisible, they are extremely strong, and they aren't very good standalone creatures. Blazvatan is a tank of a creature. It has extremely high energy, two stats that are over 140, two elements, and two element Xs. There isn't much stopping that except for going around it and destroying the conjurers, which again isn't very Mipedian-like. The only thing I have to say is that the warbeasts are pretty bad Mipedians flavor wise! They were created through pure mugic, so I guess you could say it is because of the Mipedians great skill at mugic, but other than that... :P
One other thing I want to touch on is the Mipedian's unique ability of sacrificing themselves to help out their comrades in battle.
Tianne,
Sobtjek and even the new Mipedian
Alazdan all embody this. They would rather sacrifice themselves than see a friend be destroyed, so they believe in putting the needs of the group ahead of the needs of the one.
Mipedian's weakness seems to be with water, which makes sense seeing as they are desert dwellers.
So comment, rate, yell at me for missing something, anything works!
