How do I make the damage of a weapon splash skill be divided among targets?

[bodibastos]

I'm trying to make the damage of the skill Magnum Break be divided among all targets. However, even though I changed the properties in skill_db, this isn't happening. From what I've tested, the division only works with magic and misc type skills, not weapon type. Does anyone know how I can change this?

 

This is what the skill_db.txt looks like:

7,0,6,4,3,0x6,2,10,1,no,0,0,0,weapon,2,0x0, SM_MAGNUM,Magnum Break
