How would i...

[svedin]

i don't know if this is the right one. but try to change "ItemLimitCategoryID"

[namelessgnome]

How do i make it so people dont ever lose durability or something to that effect?

There are two ways to do this, either you do a core edit, removing the code that damages the items or you do it in the database. The database edit can be done with the following SQL query
ON THE WORLD DATABASE

UPDATE `items` set MaxDurability = 0;

EDIT: You probably want to reset the players durability too you can do that by executing the following query on your character database

UPDATE `playeritems` set durability = 0;

how do i Remove Arcemu info on logon

That is sent in CharacterHandler.cpp
In CharacterHandler.cpp find "SERVER:"
add "//" at the beginning of that line and recompile

how do i remove the spell res sickness?

That one is bit harder. Sadly I can't post a patch with that as you are using ArcEmu and I'm using Aspire but If you know C++ you can look in WorldSession::HandleSpiritHealerActivateOpcode and remove the relevant parts

Thank so you much Nameless Gnome for answering just about all my questions.
Edit: Svedin, thank you it works. I tried messing with it before but it didnt seem to work but this time i guess it did thanks
Edit: the durability fix made throwing weapons not woork

[namelessgnome]

Oh damn! Durability is the ammo count for throwing weapons... Sorry man. Lets see if i can fix it.
EDIT:

I think this will work

UPDATE `Items` set MaxDurability = 999 WHERE  `class`=2 AND `subclass`=15

I cant lie...I think I love you...

Edit: It appears daggers also have the same tags...so i think ill just manually add durability to the throwing weapons that will be used but I still love you.
