IMO there are at least 3 differ
3- Moonlight greatsword build: this one is a special build because you don't need to put many points in att, but use the R2 attack instead and always have repair powder on you to repair the weapon. Repair powder = Fresh/Old Spice in Demon's Souls in this case.
Vit > 20
Att 16
End > 20
Str 16
Dex 12
Int 40
Fai 8
Don't even need anything more than 12 or so Att for MLGS, really. You just won't be casting much, if at all. Same goes for Dex; 10 for the sword itself is sufficient.
Another benefit is that because the MSGS is so good, Int becomes a viable stat for just raising your AR, and as a result you can also stack Vit to 40+.
