What is "Power" for on a Runekeeper?

I have a spell (Self-Motivation) that says it will increase my Max Power.

What is POWER used for ??

Power is the blue bar under your green morale bar. If you read the tooltips you may see that some skills use power to cast. It's not really an issue these days as power restoration is quite high for most characters. But that is the power that skill will restore.

Thanks. as a Runekeeper it never really goes down, or it is getting recharged so quickly, which is great.

Power was once an important resource for healing and support classes to manage.

ICPR used to increase with the square root of Fate. Now it increases linearly, and there is so much passive/free regeneration that power is basically irrelevant.
