Nope at first was 40 then tried 100 still miss miss miss :S
I don't know if it could be a script conflict but only scripts I have that affect the battle system are the atb, front view battle system, invisible battle back, custom message system, indirectly but stats points to level (Which shouldn't affect it anyway but to add it just incase) and have a script requested for my game that adds status effects on your characters when you equip certain weapon/armour types. (None of the stats makes it impossible to hit)
The last script does this:
If you equip a hammer you get the hammer effect which boosts hp, damage but lowers defence, accuracy (By 15%) and maybe something else.
I haven't tried without it but yesterday I was able to hit with the skill but today don't know why as I haven't changed anything (Well tried a new script but removed it from project just incase but still missing all the time with skills but not with normal attack)
[Edit]
Nevermind it is the script that adds stats to the weapons/armour >_> great....
Hope it's my fault not of the script as the guy who made it takes a lot to edit scripts sadly.
This can be closed.
Thanks blizzard anyway.
