Black Halo

I'm trying to get Black Halo, and attempting to use Ayame to make Light. I've tried on BLU with Realmrazer and WHM with Hexa Strike, but in both cases, she doesn't seem to any WS that can make the SC. Am I doing something wrong here? I've been using AAEV as my tank trust, and I wonder if she's messing up the SC.

Go to Ceizak from E. Adoulin, hang lefts until you hit the beach with Urganite. Summon Ayame, 2 WHM, 2BRD and set up a SC with Ayame. Urganite will take reduced damage and you can complete a trial within 30 mins.

Thanks, but which WS do I open with? Realmrazer or Hexa?

Ayame goes first in WS order once you both have 1000 TP and will try to open the highest tier SC for the weaponskill you used last (so you need to use one to prime her). Im not sure which to use to get a t3 sc, just try them all til you get one.

Sadly Ayame cant open for Light for Whm club, either ask a friend or try Ferreous Coffin, he will use Randgirth which will make Light with Hexa Strike/Realmrazer.

Noillurie is locked into using Kaiten right at 1k TP. And she has a 4-hit build.

Kaiten -> Hexa = Light
