Signature ability

A signature ability is a special type of ability that is only available to tier 4 classes.

Each tier 4 class has 1 signtaure ability.

All of them are named a "wave" of some kind. All of them have an AoE effect on either allies or opponents. Using each ability requires a completely full adrenaline bar.

Unlike normal abilities, which have 5 levels, signature abilities have only one level. They also do not require skill points and are available upon class selection, assuming you have the Logos required for use.
