If a level 10 chronomancy wizard ritual casts water breathing could they use arcane abeyance to put it in a bead for later?
Arcane Abeyance only works with spells cast using spell slots, which ritual-cast spells are not
The Arcane Abeyance features states (emphasis mine):
When you cast a spell using a spell slot of 4th level or lower, you can condense the spell's magic into a mote. [...]
However, the section on "Rituals" states:
[...] The ritual version of a spell takes 10 minutes longer to cast than normal. It also doesn't expend a spell slot, which means the ritual version of a spell can't be cast at a higher level. [...]
Because ritual-cast spells do not expend a spell slot, they cannot be used with Arcane Abeyance.
