Actually im quite shocked if we are talking about numbers, because aspected helios in nocturnal stance is now stronger than succor(except that its slower), because of 5% healing increase in nocturnal sect. Our shield is now 157.
Alp. Benefic shield is now 130% of HP restored, it used to be 250 heal + 250 shield, now it is 250 heal + 325 shield?? Plus 5% nocturnal sect healing buff makes a shield 341 ? And an instant cast. That's stronger and more reliable than adloquim.

CO is still kinda meh, but at least it will come up at the same time as your LU comes up.

The cards being 30 seconds now is pretty decent as well, its still RNG but at least longer.

And CO now also works well in nocturnal, i just still will have to test if u can move when in it. I dont get much the auto attack thing. Is it probably the same channeling ability?

All in all: nocturnal sect received massive buff, in nocturnal sect we actually have 5% stronger heals than other healers. We still lack emergency heals, but im curious how it will go with these changes
