Let us play a board game if you will.
Renaud's axe TP Bonus +1000
We can use these two sets as a speculation or base build. Not to include zone buffs.
Spells used that can be used to enhance accuracy.
Sword Madrigal: 85~
Blade Madrigal: 114~
Honor March: 58~
Hunter’s Roll: 85~(Regal)
Precision: 50(Idris or Bolster)
Sublime Sushi: 100Acc
(Not)Maximum/Close Max Acc+ Buffs~ : Total > +492
It is some what a rule of thumb to use Sushi, Blade Mad, Vic March, HM on just about everything 129+ while a BRD is present in party. Usually leaving 1-2 slots open for buffs. Could use another Mad and/or Mineut V.
When a Geo is present in a melee setup vs w/e a Geo is going to use Ifury, GeoFrailty leaving an option for an entrust precision.
Cor present is usually going to use a variation of Chaos/Sam, Fighters/Sam, and maybe but unlikely Fighters/Chaos. If convinced Cor could use Fighters/Hunters, Sams/Hunters.
After over looking some very old post on reddit 1200 acc is goal for most content 119-129.
1300-1400 for ilvl 130-140ish
1400-1900 for ilvl 145+
If you had these buffers at your disposal you could end up with 1465 accuracy making it usable on higher content. Plug and play.
