Maximum Reduce mana reserve

Hey, I'd like to know if it would be possible to have 100% reduce mana reserve.

In the skill tree, there is a total of 38% reduce mana reserve, and a 50% less mana reserve behind Blood Magic.

First of all, I'd like to know if they add up, for a total of 88% reduce HP reserve (because blood magic). If so, and using multiple Conqueror's Efficiency (2% reduce mana reserve per jewel, so 6 jewels), it would add up to 100%. So you could run all the auras without any reduce in HP.

I feel like my math is wrong, I may not understand well Reduce vs Less and the interaction between both.

Thanks!

no. more/less are standalone multipleirs. applickable mods with increased/reduced stack into one multiplier

youd have 0.5 * 0.5 -> 75% mana reserved

you can also count prism guardian, alfa howl and so on

max reduced on tree is 38%, you're correct here.
then you have alpha's (8% reduced), skyforth (6%) and the jewel (2% because is limited to 1)
100%-38+8+6+2: 46% -50% (BM): 23% of the original reservation

additionally you can run 3 auras on the prism guardian, which gives another 25% reduced
46%-25: 21% -50% (BM): 10,5% of the original reservation for 3 auras

You can also use Victario's Influence to get 20% reduced reduction with your chest auras, but that's only useful if you are making an aura support character.
