This is what i suggest for low-end gear
Head-Top: soul ring or any
Head-Mid to Bottom:Any
Weapon:x4 Hurricane(Andre) mace/blade
Armor:Holy(Angeling) Full Plate(or w/e armor that has good def)
Shield:Anti-Medium(Tirfing) Guard
Garment:Immune(Raydric)/Deviant(Deviling) Muff/Manteau/Pauldron. Thou, you better get angeling 1st before equiping devi garment.
Boots:Can be just a normal upgraded boots. Matyr/Verit aint really that good, cause more hp = more dmg from your own GC.
Accessory:Teleport Clip or anything that adds str/int/dex or reduce cast time.
Thats all.. unless you already have decent/better gears.
The problem w/ crusader gc build is that.. They're a pain to train at start, unless you have help.
Cause If you go For GC 1st then you wouldnt have heal and vice-versa.
So for leveling place..
You'll have to spam meat and Gjs alot at these stage.
Stay at leaf cat 1st. Just for the job lvls, say till job lvl 25?..
Or till you get a decent GC lvl...
Thou you dont need to max GC lvl at 1st. Maybe till lvl 5~7 then get your heal.
Then Maybe Prison. You can even get to job 50 here...
Now on the Awesome Stage

When you already have all the skill needed, Gc and Heal...
You can now try Nifing w/ lolis. Less ppl here than dullies.
Meaning, good exp and good farming place... IMO
Well thats about it.. =/
