I'm no expert on this, but I'll give my 2 electrums on the subject anyway.
I use 2x modifier for single activation cost, here: Pegasus 6*1*2=12
.
In this case I'd count FFs with 1x modifier in quanta generation: 6*1*1=6
.
Quanta Usage: 52
& 35
Quanta Generation: 0,5*12+6+1= 13
& 0,5*12=6
Quanta Index:
52/13=4 &
35/6=5,83
I'd start testing with changing to 8
Pendulum and 3
Pillar
QG: 0,5*8+6+1=11
& 0,5*8+3=7
QI: 52/11=4,73 & 35/7=5
PS. I'd use Owl's Eye instead of Morning Star, because it can kill Otyugh & Maxwell.
