Where is the Aurorum material at?.
The Party composition atm is, Divine soul, cleric, selfish rogue who cant work as part of the party, a social rogue who does work with the party, Wildshape Ranger.
Book of Exalted Deeds is where aurorum is from. It can be reassembled if it's ever broken, so you don't have to worry about ammo breaking when it hits (toss returning on there to pull the pieces back when you fire it and you won't have to collect them afterward).
Sounds like you could use a buffer, rather than a blaster. You have the direct-damage stuff taken care of, so supporting your team would be ideal. A buffer-ificer is the way to go, so build yourself up for buffing your party, and it won't matter how powerful you are; they'll be just as good as you are. I say make lots of buffing scrolls, such as
haste and
polymorph, and do the spell-storing
dye arrow thing with archery as a secondary focus, and you can be both a buffer and a direct-damage dealer with archery if you like, though I'd focus less on doing damage and more on buffing, personally. To keep yourself protected, feel free to make a few perma-minion scrolls to keep yourself bodyguarded (but don't throw them into melee unless you want to give the rogues flanking opportunities). Some
animate dead scrolls and some black sand would be good for this.
I can play a Wizard, but its limited due to the fact it doesnt have spell trigger item.
No idea what you're talking about here. Mind going into more detail about what you mean? Because wizards can use spell trigger items just fine; you'll just have to make some for yourself, if the DM doesn't allow you to get any otherwise.
My DM incurs XP penalties if you go a Rogue 1, Fighter 10 and your favored class in a Cleric. Type of deal.
Then don't multiclass. Artificer 20 would be your best bet, by far, whether or not multiclassing penalties are in effect (which are stupid anyway, to say the least).
As I said before the versatility of an artificer is appealing but at the same time playing one is a challenge, which for the moment is what im looking for. Artificer is as challenging as you can get in my book.
That's the gods-honest truth. Artificers are one of the most complicated classes in the game, what with all the bookwork, especially upon character creation.
As for the build, I'd suggest looking up some craft cost reduction handbooks, build yourself some dedicated wrights (Eberron Campaign Setting) take feats such as Apprentice (Crafting) (DMG II), Extraordinary Artisan and Legendary Artisan (ECS), Magical Artisan (Faerun Campaign Setting, I believe), and a couple of warforged artificer ACFs (Races of Eberron), and you should be well on your way to making your crafting pool outlast your available money by a good long margin (which allows your party to chip in if they want you to craft for them). It's good stuff.
