Refining the Concept
I worked on him a lot tonight and here's what I have so far.
Backstory: The secret forge run by Lord Merrix d'Cannith has been tinkering with the standard formula of a warforged in hopes of improving it. In one particular experiment they tried adding a crystalline element to the adamantine matrix of the body armor in an effort to improve it. The test was considered a failure, and the product, labelled in chalk IU5924 (the IU meaning Inoperative Unit), was junked by flinging it into a deep pit near the forge where top secret trash was flung before it was obliterated. IU5924, whose inoperativeness was vastly overrated, self-activated with a Psychic Warrior imprint from the effect of the crystal mixing with the martial magics applied and activated his sole power, Catfall, to prevent damage to himself from the fall. Upon landing he climbed his way out of the pit, slowly - climbing is not easy when made of adamantine. When he arrived at the top he realized he knew... nothing. So he began to explore. No one stopped him as Warforged are common in House Cannith, and he left to explore the world as a more or less blank slate (I plan on playing him with a personality similar to an early Data/B4 - intelligent on the grand scale but missing key concepts which are foreign to his nature - sleep, food, gender (he does not have one imprinted as his construction was aborted before full completion), breathing, emotions, etc. He has found and discovered he has skill with a greatsword. I am Lawful Good. Whenever Merrix discovers this experiment to be less of a failure than thought he will make efforts to recapture and study his product.
He will be adventuring with a Longtooth Shifter (CG I think) Scout (planning on heading towards Highland Stalker), a Human (NG) Monk (slightly modified) high born scion of the House Deneith bearing the Least Mark of the Sentinel, but a House Renegade rebelling against the commercialism of his house and being pursued and pressured to return by his family. There is another character, but I don't recall it off the top of my head.
I'm no longer looking into going the Artificer route. After this level I'm going to be a Psion/Cleric (agnostic: Domains Artifice and Healing) moving towards
Psychic Theurge.
Problems with the build, that I can see, are multiclassing penalties, and potential difficulty getting healed, although I made sure to max my Craft(Blacksmith) skill so he can at least try to repair himself. What do you folks think? How can I best optimize this concept.
