So I have this ability Mage Light. I morphed it into Inner Light. Essentially, what it does after the morph is: reveal hidden players within 12m, reduce max Magicka by 5% (cost), and improves my Spell Critical strike chance by 17%.

Weapon Abilities run off of Stamina, and Class Spells run off of Magicka. But Staff Abilities run off of Magicka too, though they are technically weapons. I am using a Restoration Staff as my secondary weapon so that I can Heal when in a group. Currently, I have Healing Springs and Regeneration slotted. Both of these abilities originate from my Restoration Staff, but pull from my Magicka. Here is my question:

Am I receiving my +17% Spell Critical Strike chance when casting my Restoration Staff Abilities for healing, since they draw from Magicka and as such they are considered Spells;

OR

Are Restoration Staff Abilities always constituted as Weapon Abilities, and are thereby not granted the Inner Light bonus to Spell Critical chance?
