[Clientless] Define if a skill is a buff or not (with target or not)

Hi everyone, i'm making a clientless autobuff bot for heroic pexing and i want to define wich skills is a buff and if he need target or not, i'm not sure if this information is in the Skill.dat of NSgtdData.NOS file, i've found, range, mana cost, cooldown, cast time but i can't really find what i'm looking for.

Thanks

Edit : I'm not sure but

SP1 Mage Fire Buff is :
TARGET 1 2 0 5 2

1 = Target (1 = self, 2 = self & others)
2 = ???
0 = Range if the spell can target others
5 = Range if the spell is shared in area
2 = Define if it's a buff (0 = damage skill, 2 = buff)

5th (last) value in TARGET should be enough for this.
0 - damaging skill
1 - debuff for enemies
2 - buff for allies
but be aware that buff can also mean mage sp2's heal or mp recovery and stuff like that.
but if it's 2 - it can't be used on an enemy, so it should do the trick.
