Icefend

Icefend can be learnt from the Mojo-Dojo as an auto-ability for at least most characters.

It adds an ice-element to attacks and reduces ice-damage done to you.

Because of this, it can freeze enemies feet, making them slow/have to stay in that place almost.

Since it reduces this and adds this, it is useful for when attacking since,

you can defeat and escape harm to get healed by Princess-Lola with more ease.

Since this is an auto-ability you may equip 3 others if you have this one,

equipped and no others so, you might want to use some of the most useful for a character you are using.

It's LV may increase at the Mojo-Dojo and possibly by Weapons/Rings.

Since it is an auto-ability, it costs no MP, and requires no button to be pressed unlike action-abilities.
