So, did some testing. My chanter buffs suppress armor enchants yet are unaffected by active spells/modals. For example:
-- Minor Ring of Protection
-- Wary Defender
-- Holy Meditation
All of these stack Will. Since they are equipment, passive, and active, respectively. Now adding a phrase into that mix:
-- At the Sight of Their Comrades, Their hearts Grew Bold
The Minor Ring of Protection gets suppressed, everything else stays. So, are phrases classified as equipment? This behavior is consistent with other phrases and spells.
