The Ashbound Initiate, Gatekeeper Initiate, Greensinger Initiate, Warden Initiate, and Winter Initiate feats all lack ability scores for their spell save DCs and attacks. There may have been an oversight when these feats were designed but I'm sure that's not what was intended. It's the same problem that the new spell school adept feats from Arcana Unleashed have.
I think I'm having the same issue with these feats as you are, but I'm seeing them work differently from the Arcana Unleashed feats. With Arcana Unleashed, I can select the version of a given Adept feat that matches my spellcasting ability (e.g. "Evocation Adept (Charisma)"), and that ability's bonus is applied to my spellcasting DCs for the appropriate spells. But the FoE druid sect Initiate feats don't have ability-specific versions, and aren't applying my spellcasting ability to the spells they grant.
Any word on fixing the Voice of the Fury/Shadow’s Gift feats not preparing spells? I really hope they get an update soon
