Item scripts on the database

I'm trying to understand what these means, the items that give a "chance" to inflict something.

Bloody Roar

{ if(getrefine() >= 9){ bonus3 bAutoSpell,"NPC_WIDEBLEEDING",2,30; } else bonus3 bAutoSpell,"NPC_WIDEBLEEDING",1,30; },{},{}

It says when refine is +9 it's 2,30 or else default would be 1,30. What does this actually mean? is it 2 out of 30 hits or..?

Also look at this

We know it's 5% chance, but it says 500. I don't get it.

Well, usually the first number indicates "level", and the second number is %. In this case, it's a 0.30% chance. A 3 would be 0.03%.

I read it as Level 1 Wide Bleeding @ 0.30% chance with Level 2 if >+9.

Maybe Level 2 Wide Bleeding has a better AoA?

[Zereges]

Yes it has
Level 1 - 5x5
Level 2 - 11x11

In the future, the easiest way to find out is this http://eathena-project.googlecode.com/svn/trunk/doc/item_bonus.txt it's the official documentation in the eAthena trunk on how bonuses work.
