Harden

This is an auto-ability learnt from the Mojo-Dojo.

It grants equipper a defense boost making them less-vulnerable to attacks.

This is different than Surge quite the opposite since serge is for offense and this is for defense.

Being an auto-ability it activates automatically instead of pressing buttons.

Like all other auto-abilities you may equip up to 4 total.

Since this is a non-unique ability, you may equip it to more than 1 character.

Some Rings may have this ability. If they do, then, it will boost it's LV by said numeral.

This ability will increase defense by greater amounts for every LV.

You may LV up this ability at the Mojo-Dojo.
