Oh those are [enchantment (compulsion)s], a kind of [enchantment]!
If hypothetically they were built into a [magic item] that would make it [cursed], but she can't get off just the sense of language whether it'd be easy to [curse] a [Belt] with an [oath]-breaking [enchantment (compulsion)] specifically.
[oaths] are very strongly tied to something called [Lawfulness], by the way; a word with a sense of depth about like an ocean opening up under your feet.
