Masteries with mana reservation efficiency for other auras

There are different Masteries in the game, among which there is an increase in the effectiveness of reservation a skill that fits the theme. Armor has Determination, Accuracy has Precision, Life has Vitality.
Due to the fact that you removed the mastery for a increase efficiency reservation, the question arises: Can you give us an alternative?

We have Fire Mastery for Anger, Cold Mastery for Hatred, Lightning Mastery for Wrath, Chaos Mastery for Malevolence, Physical Mastery for Pride, Critical Mastery for Zealotry, Resistances Mastery for Purity of the Elements, etc.

Give it to us, it'll be fair.

Well, looks like your only way of getting those, would be by getting the small cluster jewel, with the appropriate mod (6% inc reservation efficiency + noteable)

Those are actually stupidly potent, giving you 50% efficiency for most relevant auras in the game, (Purities, Elemental damage, Malevolence)

We have those, but they are available on influenced amulets.
For example Crusader amulet offers:

-Discipline (50-60)
-Purity of Lightning (50-60)
-Wrath (40-50)
-Zealotry (40-50)

This is pretty solid, as mastery on the tree offers 25%.

Ashes of the Stars offers general 20% reservation efficiency.

Shaper Shields offer up to 30% for socketed gems (you can socket 3 auras, or two with Enlighten Support).

Generally you have to invest more in order to get as many auras as you got in 3.18.

30% reservation + recover 5% life when you block is pretty solid shield, it doesn't have max res like AA but it's decent. Both those affixes are Shaper and recover 5% life is craftable with harvest (life tag)
