What abilities does power-lv affect?

[EmilAmundsen]

Do we have a clear view on what abilities/spells power-level affects?

[Silvaren]

In game encyclopedia says that power level affect all spells and abilities, but I know that some things scale with character level instead.

The Accuracy, Damage and Penetration of Summoned Weapons, for example, scale with Character Level rather than Power Level, however their Duration still increases with Power Level. I suspect similar things are true of all Spells/Abilities.
