With that in mind, I would propose current best sets to be(prioritizing enmity cap > cure/cureskin strength > haste cap > conserve mp):
Single Target Cures(Raetic)

Haste on cape. Head Path B, Feet Path D.
Day/Weather Swap:
Austerity Belt +1 > Hachirin-no-Obi

Regarding Mission Rewards:
If no magnetic earring, Calamitous or any other conserve mp ear replaces it in any set.
If you have Janniston Ring, it will replace Kuchekula in any of these sets.
I made my sets with cleric's torque +2 because I have them. I am not advising you purchase it or prioritize it, which is why explanations for substitions were given. You gain haste cap and/or a bit more conserve MP by using it, nothing ground breaking. With the torque +2, you are more likely to want a haste augmented cape and path D bliaut, while a torque+1/nq owner would want a cure potency augmented cape(they would still keep path D bliaut if they have theo body+3 to cover enmity needs, but change to path B if not).
Theophany Bliaut +3 can replace Kaykaus Body in any of the sets for minimal loss. Kaykaus D has slightly higher cure power, same potency, and some conserve MP if the enmity is not needed, though.
