Thank you but I meant Guile is tier 2, so Psionic's tier 3, suppose I should have clarified I was phrasing it as [Tier X Tag] and not [Tag Tier X]. How does Tier 3 Psionic handle Tier 2 Guile's "You have a Trick that applies to a single Approach; invoke it before you roll to gain +2."? That quite explicitly mentiones Approaches does. Do I, like, replace Approach with Effect...?
Edit: And what of the Every 4th Level benefits of The Specialist? Is a Class Tag of another class they take first tier of then treated as a Specialty? If so then can they increase the Tier of it on future levels? If sonthen how's that deal with Effects/Approaches?
