100% aura reservation reduction possible ?

Im asking if I get 100% aura cost reduction, will they cast for 0 hp with BM some1 tried it ? =P

40% node from BM, helm 8%, 25% shield , 21% witch tree + 15% from other tree is possible for pick = 100% aura reservation reduction + cost reduction gem etc

BM (and reduced mana) multiply, they don't add.

still is over 100% without gem, sheild helm and all nodes

Did you read (and understand) what olop said?

Taking everything on the tree related to reduced/less reservation, you'd end up with
46% reduced mana reserved
40% less mana reserved
8% reduced mana reserved from Alpha's Howl
25% reduced mana reserved for auras socketed into Prism Guardian (3 at max)

Now for those three (I assume 60% base reservation) in Prism Guardian you'd get a reservation of:
60% * (1 - 0.46 - 0.08 - 0.25) * (1 - 0.4) = 60% * 0.21 * 0.6 = 60% * 0.126 = 7.56% reserved life per 60% aura

Even when using a level 20 reduced mana gem with 2 of those you'd still end up with some life being reserved as the reduction from reduced mana gem is also multiplicative with the others.

i think the math goes something like this...Using a level 20 Reduced Mana Gem (.71 mana multiplier), your example reduced mana nodes and gear (1-.69), and Mortal Conviction multiplier node (1-.4), I think the mana reserved would be

.60 * .31 * .71 = .132, so a 60% aura would reserve .6 * .132 = 8% of your max life, or maybe 9% depending where the rounding occurs.

For Aura Reservation, only X% Reduced Mana Reserve will apply.
There is currently a total of 46% possible reduction available in the
Passive Tree and 40% less reservation from Mortal Conviction, though
it would take you on a long path to obtain it all.

After getting the nodes, the only other way to reduced the Aura Reservation
cost is by linking the Aura Gems with a Reduced Mana Cost gem. This gem
is multiplicative and not additive. A Lvl 20 Reduced Mana Cost
gem gives a 61% multiplier. Quality doesn't apply to reservation costs. (Thanks!)

Any math for Aura Reservation would look like this with both:

(Original Aura Reserve %) * (1.0 - .46 - X)* (1.0 -.40) * (.71) = New Aura Reserve %

An Example Using Numbers

60% *(.54)*(.6)*(.71) = 13.8% which will round down to 13% Reserved


Please note that neither increased Mana nor reduced Mana nodes is applicable for Mana Reservation.

Assuming they are additive, if there are Uniques that have "X reduced Mana Reserved" then you would add those totals and replace X with that amount. The Alpha Howl and Prism Guardian give 8% reduced and 25% respectively (assuming you have the gems in the gem slots).

Example with The Uniques

60% * (1.0 -.46 -.33) * (1.0 -.40) * (.71)

60% * (.21) * (.6) *(.71) = 5.37%

So the lowest you can get for one 60% Aura Reserve skill is down to about 5.37%
of your total health, which will round down to 5%.

If for some reason the Uniques are multiplicative instead, then we have
13.8% * (1.0 -.08) * (1.0 -.25) = 9.5% , which will round down to 9%.

I hope that clears a lot of things up for you.

The quality bonus from the reduced mana gem is not applied to mana reservation. Therefore, there is no difference between a lvl 20 and a lvl 20 gem with 20% quality for that purpose.

Ty. And fixed. Learn something every day =)

nvm

Aura reservations are rounded up, not down. At least somewhere in the equation. Otherwise you could always run a 60% and a 40% aura, which you currently can only do if your max mana is divisible by 5 making it so there is no rounding necessary.
