As of this writing, part of the Aetherpact tooltip for Scholar is... ambiguously worded and implies non-existent functionality:

The Faerie Gauge is increased when a faerie is summoned and an Aetherflow action is successfully executed.
This implies that if you summon a faerie or use an Aetherflow action (at any time), the gauge could increase, which is not correct. It only happens during combat and only by using an Aetherflow action; faerie summoning doesn't directly increase it. My suggestion is changing the wording as follows, to remove any ambiguity as well as to clearly explain the two restrictions:

The Faerie Gauge is increased when an Aetherflow action is successfully executed during combat while a faerie is summoned.
