How do I reach 450 in T8 as MNK?

[Kuroyasha]

Hello all,

My grp has beaten all of Second Coil, so i've been trying to set individual goals for myself to keep things interesting beyond the hope of a mnk drop. So i wanted to see if i can reach a new dps height

Ive seen around that some mnks are getting around 450 in t8. How do you do that? Will my gear need to be better or is it about the items im using/not using and rotation?

I have: 110 tome weap
high allagan head
soldier body -i100
high allagan belt
myth pants
allagan feet(i90)
mog choker
high allagan earrings
myth/allagan wrist
soldier ring- i110
myth ring

Current mnk ilvl = i100

I use buttons in a blanket, but I dont use any potions. Sometimes i wont use food either tbh. W/ and w/o food i post around 420 for the full encounter,w/ highest being 423. Will I need to pop x-potions of strength to reach 450? Is my rotation just not right? I haven't tried keeping up fracture throughout whole fight either. I drop it when i see my tp getting low and invig is not quite back yet. Will I have to keep it up whole fight to reach that height?

Any tips from mnks who have posted that high would be appreciated.
