Um, could you show us what code you do have?

I cant believe your having trouble with Class changing, the pricipals for class changing are INCREDIBLY Simple!

Seriously, you change a variable to something else, here ill give you a quick lession using diablo classes

Warrior, Rouge, Sorc

Im a Warrior and i create a new character

I level as a Warrior, and it calls the proc to check for it

the variable, hp, maxhp, class, level are all predifined

proc/levelup()
<tab>switch(class)
<tab><tab>if("Warrior")
//Give warrior Stats!!!

Since my class is warrior ill get the WARRIORs stats

<tab><tab>if("Rouge")

my class isnt Rouge, so i wont get rouge

same goes for wizzard

now when i class change it gives me a nice list of classes, and i pick say a rouge

the variable Class
changes
like so

class now equals "Rouge"

so when i level, i get Rouge Stats
Its pretty simple really, just...keep the KISS rule in mind

Keep It Simple Stupid

Nuff said

I still dont get how to do monsters
