How do you use geos?

First you equipt the geo you want to use, then, in battle, instead of using a combined attack, (after you charge the gauge) the geo will activate.

Defeat Krux then equipt a geo. In battle, fully charge the lower middle bar then press Y.

What he sai but when it gets charged up enough you just click Y. Not B

if you want to equip the geos go into the prizmod,go in to battle set,click on rallen then click on the small icon of the geos and drag the selected geo to the equip icon.

But first you have to get adlous where you find him crashed where maja is

You have to beat the game first, then the geos work

When you face kruxes krawl, there will be this kragon with 30000 hp. You can't defeat it, so a tindera (flame geo)comes out. After the game, you first should go into your prizmod, click on equipment and there will be a list. On the bottom it should say geos. Click on that then press equip geo. When your battling krawl, just wait till your ch gauge is high enough then press y. The geo will then destroy the whole thing. (note, your spectrobes wont earn any hp)if you want to obtain geos, go back to kruxes room and go into the krawl os phere. There you can select your level you want to go into and the more levels you complete, the more geos you will get!. Hope this helps!
