Alright, results....
Weapons at starting area of ro'maeve have the following skills attached to their souls
Code:
FP Ability
38 Auto Regen +5
23 Instant Phalanx
17 Instant Stoneskin
17 Instant Shell
17 Instant Protect
17 Dex +25
12 Instant Aquaveil
8 Beast Killer
Phalanx, Stoneskin, and Aquaveil I only found on RDM type weapons (Ominous Weapons), Auto-regen I only found on a war weapon, though it could just be pure luck that I even got it, everything else I could find on both Killer (war) and Ominous (rdm)
Phalanx Plate with crystal
phalanx didn't stick with weapon
weapon was level 7
Main: War
Sub: Blm
FP 0/71
Auto-Regen Plate with crystal
Auto-Regen didn't stick with weapon
weapon was level 7
Main: War
Sub: Blm
FP 0/71
both Rdm and War weapons therefore become War/blm, level 7, with 71 FP total
The Instant Aquaveil, Instant Shell, Instant Protect, and Undead killer plates stuck with the mob upon crystallizing, and the Undead Killer also came with 15% attack, all remained with 0/71 total FP
Open to suggestion on more stuff to find out and stuff
And yes, I realize that I may not have gotten every skill that comes from weapons, that's just what I got with 60 soul plates
