One last thing I've failed to mention about Switch Axes:
(Skip to 0:55 and watch through 1:11)
Switch Axes in Sword Mode can discharge to make an explosion, but they will have to be reloaded, depending on the meter in the upper left (At full energy, Axes can discharge twice before reloading). As far as the RP is concerned, this can vary between a pure mana explosion, a water explosion, or an ice explosion. As for reloading, Finir can just create a watery orb and 'feed' Nimi, or, just like in the game, allow her to regenerate this energy over time.
That is all for the Switch Axe.
