I have mentioned this before on the forums, but I wanted to make a thread so I can go a little more in depth with it and so it is easier to find. Bishop's are an amazing one shot grind char, especially after you add Spellboost into the mix
. To utilize spellboost you need to reduce your Mp consumption, and increase your Mp recovery to balance out the heavy Mp cost.
Do not use any equips with Mp consumption+%, Mp recovery-% or Max Mp-%.
The reason to use spellboost crystal rather than a Resty Rod is because you don't need to rely on getting hit, and for the Glass Cannons like me, getting hit just isn't an option. Also 10 seconds is just too short to switch out to a superior weapon.
You will need at least 2 blue lines with 100 Blb. Make the other 6 M attk lines.
I highly recommend using Struggler and White Maid Headdress as they will boost your Nemesis damage higher then any other equip combo. Staff is up to you, but the most powerful staff you can get your hands on is what you want. (Empress last up when its released is phenomenal)
Your choice of staff/ Gerust ☆lvl 4 Mp cons
Struggler or Cleric Robe/Moldus ☆lvl 5 Mp cons
White Maid Headress, Ecarlate, Itiance up or Medic Pouch/ Spellboost ☆lvl 4 Regeneration
Accessory ☆lvl 5 Regeneration
Your choice of special/Mezzaluna
With just the stuff outline above, you will still need to be cautious about using Quick skill, as it does give Mp recovery-%, but it can still be countered. If you can get a Battery, Leafy Bangle, or Rustling leaf Earing slot version, you can use Quick skill freely and you can start removing some of the abilities, but always keep Mp balance in your mind, you need to be recovering faster then you use Mp.
I personally use:
Caterina/Gerust ☆Int lvl 3
Struggler/Moldus ☆lvl 4 Mp cons ( Lvl 5 degraded to 4 in transfer to Struggler :/ )
White Maid Headdress/Tarna ☆lvl 4 Regeneration
Accessory ☆lvl 5 Regeneration
Rustling leaf Earing/Mezzaluna
I get spellboost now from Pet skill
Edit: Something I forgot to write is, you need to have Dex at least at 300 as well to make spellboost last long enough to recover the cost of casting it.
Another Edit: I am no longer a glass cannon due to using Struggler, my build is now Int 416, Vit 170, Dex 401, BL 100, GL 100.
