"As an immediate action, the wearer can expend up to 4 arcane pool points stored in the ring to use the reflection magus arcana."

Do I need to possess the Reflection arcana myself to use this or do I not?

No, but you need to have arcane pool points.

[Arkwright]

Certain? Much thanks.

[wraithstrike]

Yes. The ring says you need arcane points to use the ability. There is nothing saying you need the ability itself.
