My 2 cents

[BG-57]

1. Accumulate=greatest
u can have ramza sit in a corner whateever job you want, sub squire and use accumulate...instant xp!!!

Agreed. Basic Skill or Guts are the standard secondary skill when I level up Ramza and generics. Steal Gil work well on immobilized foes when I level up nongenerics like Agrias or Mustadio.

Gained JP Up is a must-have when leveling, although I consider Gained Exp Up overated. You'll reach level 99 long before mastering every profession anyways.

2. Permanent Brave up and Faith up
Using a calculator or bard or something...u can raise faith and brave but if used on Ramza, it permanently increases it

The formula is for every 4 points of Faith or Brave is raised (or lowered) in battle, it will permenantly change by 1 point. This applies units other than Ramza as well.

3. Knights without swords
I always did this and this kicked serious ass!
Jsut having the monk powers and using equip armor or somthing like that makes you super strong

Indeed, Monks with armor are cool.

While none of your suggestions are news to me, they are nonetheless helpful.

EDIT: Bards actually cannot change Faith or Brave. But Mediators, Calculators, Oracles, and Temple Knights can. You can also equip certain items or skills to change them as well.
