How does Healer's Hands interact with the Superstitious rage power?
I'm trying to figure out how these two abilities interact in Pathfinder 1e.
The Superstitious rage power says that while raging, the barbarian must attempt saving throws against all spells, even harmless ones, and can't willingly accept magical effects.
The Healer's Hands feat allows you to use the Heal skill to provide healing without magic. However, it is also a conduit feat, meaning it has a supernatural (Su) component.
My assumption is that Healer's Hands should still work normally on a barbarian with Superstitious, since the feat doesn't allow a saving throw (nor does it have the usual "(harmless)" designation that spells like cure wounds do). However, I wanted to check whether there's a FAQ, developer clarification, or established community consensus on this interaction.
Am I interpreting this correctly, or is there a rules interaction I'm overlooking?
If Superstitious does force a saving throw against the supernatural healing, what kind of save would it be? Would it be analogous to cure spells and allow a save for half, or would the healing simply fail entirely?
Thanks!
