Mana reservation calculations are multiplicative, not additive IIRC. You would need 2% reduced mana reserved to make them reserve 49% each. Incorrect.
Reduced mana reserved is additive. Only enlighten is multiplicative. It only doesn't work here because of rounding.
so with 2% i free up 18 mana correct?
Good to know, thanks!
They are additive with each other, but multiply into the base value, like critical strike chance. This is what is usually meant with additive. You got the outcome right though: 2% reduced is necessary to have any effect on 50% auras.
The alternative (used for block, resists, etc.) is usually called "flat" or "additional".
well 1% from 50% is 0.5% which means each your aura has 49.5% mana reserve cost which gets rounded up by the game to 50%
