I'm trying to understand what these means, the items that give a "chance" to inflict something.
Bloody Roar (http://ratemyserver.net/index.php?page=item_db&item_id=1271)
Quote{ 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
Savage Bebe card (http://ratemyserver.net/item_db.php?item_id=4017&small=1&back=1)
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?
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 (http://eathena-project.googlecode.com/svn/trunk/doc/item_bonus.txt) it's the official documentation in the eAthena trunk on how bonuses work.
