How much mana will "Reduced Mana reserved" reduce from Spells that reserve Mana?
Here is what I mean: http://pathofexile.gamepedia.com/Reduced_Mana_Reservation An Example is Sovereignty: http://pathofexile.gamepedia.com/Sovereignty Putting points into it nets you 14% reduced mana reserved.
Let's say we have 10% reduced mana reserved
When you cast Purity of Lightning: http://pathofexile.gamepedia.com/Purity_of_Lightning Which reserves 40% mana.
By how much will it reduce the reservation?
- by -10% additive result: 30% mana reserved
- by -10% multiplicative result: 36% mana reserved
Incase it was additive: How does it work with a second aura? Let's say #2 is 20% mana reservation
- -10% of 40%: 30% mana, and 20% from the other, result: 50% mana reserved
- -10% of 40%: 30% mana, and -10% of 20%: 10% mana, result: 40% mana reserved
