FIRST OFFICIAL SKILL TREE PICS - from Kripp's stream

That kind of sucks.

Health Reserved with BM Passive:
60% * .71 * .7 * .67 = 19.97% (Reduced Mana)
60% * .71 * .7 * .59 = 17.59% (Reduced Mana + Alpha Howl)
60% * .71 * .7 * .34 = 10.14% (Prism + Reduced Mana + Alpha Howl)
60% * .7 * .34 = 14.28% (Prism + Alpha Howl)

Standard Mana Reserved:
60% * .71 * .67 = 28.54% (Reduced Mana)
60% * .71 * .59 = 25.13% (Reduced Mana + Alpha Howl)

Health Reserved Without BM Passive:
60% * .71 * .67 * 1.96 = 55.94% (Reduced Mana + Blood Magic Support)
60% * .71 * .59 * 1.96 = 49.26% (Reduced Mana + Alpha Howl + Blood Magic Support)
60% * .71 * .34 = 14.48% (Prism + Reduced Mana + Alpha Howl)
60% * .34 = 20.4% (Prism + Alpha Howl)
60% * .42 = 25.2% (Prism - Alpha Howl)

Looks like max of 3 percentage auras + clarity on mana
Could potentially get another 3 percentage auras on health if you are using Shavronne's or 2 on health at 30% reserved or 3 at 63% reserved without Shavronne's.

Prism Guardian + No Alpha Howl + Shavronne's = 6 percentage auras + Clarity + Low Health Status.

Difficult to see from the screenshots but it looks like the increase aura range also got changed to a reserved node set.

It appears it is 1 increased effect, 1 mana reserved, and 1 Sovereignty node instead of the 10/10/30 increased area set. If so, that would mean 13% more reserved that is easy to get for scions and with all these increased effects, it is likely you can get +80-100% effect instead of the old +21%.

1 more set over by CI by the crit node batch.

Any character going up to the shield blocks and going up to EB should be able to pick up all of these and by my count it's 59% mana reserved total.

Standard Mana Reserved:
60% * .71 * .41 = 17.47% (Reduced Mana)
60% * .71 * .33 = 14.06% (Reduced Mana + Alpha Howl)

EB Aura stacking should be fine.

So it seems blood magic is now the way to stack Auras, whilst relying on ES for defence.. Bye bye EB :/
