I have a certain fondness for Eberron's artificers (far more than I have for the d20 rules system, alas, so if you know a good conversion to something lighter, do point me in that direction) and so, a few ideas I used once in a online game. No stats, alas, but who needs 'em? Math is easy!
Robe of artificer's artistic area: holds a fully functional, decently equipped, if somewhat messy, workshop. The simple constructs within can perform basic manufacturing without too much supervision. Also functions similar to a bag of holding.
Javelins of minor detonation: An endless array of javelins that explode on command, vanish after a minute if not detonated before the that time passes.
Stick around sticks: Wooden throwing darts that unfurl into a small mess of constricting vines and painful but non-lethal thorns.
Kinetic klay: vials of liquid that, upon being thrown, shatter and fill the immediate area with a viscious goop that violently redirects kinetic energy. Stepping on them sends you flying into the air. Can be used both for mobility and area annoyance.
Bombtastic bouncers: Heavily bouncing spheres, each that explodes when shattered or after 1D6 rounds. Unreliable, chaotic and excellent to throw into mobs.
Stinging smoke: Tear gas in a vial!
Shadow in a box: Thick, obfuscating smoke that can be thrown! STUPENDOUS!
Shimmer spheres: Reflective, mirror-like balls that when thrown reflects light to form highly complex, very bright and utterly distracting patterns until crushed underfoot.
Slick slippers: Wrist mounted sprayer that shoots a thick stream of extremely slippery liquid that dries within seconds. Can be used to create instant oil slicks under your enemies or for a rather stylish transportation.
Choker chains: Animated chains that emerge from the sleeves of the robe. Can be used as an animated whip to bind and entrap foes or just as raw utility chains for things like climbing.
Dumb dumbs: Small, metal beetles that are attached to the base of the neck of your foe, rendering them incurably stupid for a minute or so. Expect sudden demands of MOAH DAKKA!
Riveteer: A very large, very cumbersome turret that shoots thick metal stakes at disgusting velocities. Mounted in the robe, used by pulling off the robe and holding it up like a Torero. Prone to misfires, extreme inaccuracy and painful riccochets. Ammo takes time to manufacture, gun needs time to spin up and cool down. Works excellently as a response to cries of MOAH DAKKA!
Roving Roger: A construct in the form of a humanoid rabbit that begins to chatter wildly, bounce around erratically and all around make a nice distraction.
Sky steel: Collapsible metal wings that strap onto the back. Doesn't allow powered flight, but gives enough magically induced lift to allow for nice glides and safe landings. Combined with Kinetic klay and some slick slippers for a running start and decent distance can be achieved.
FlamBéThrower: A metal gauntlet that shoots bees. That are made of fire. My god.
Mug of many mysteries: A mug that contains whatever non-magical, alcoholic beverage of your choice. That never stops flowing. Ever. Not good for the desert, good for the pub. Better still when there is no pub.
Flask of finite truths: What you drink the morning after a night with the mug of many mysteries.
Seeking scarab: A small construct in the form of a golden (okay, dirty bronze. Alright, rusty copper!) scarab beetle. It can hold a small role of parchment, enough to scribble a few sentences on (if you really squeeze the letters together) and subsequently be ordered to seek out anybody the wielder knows, at which point it will take flight and use it's magic seeking to find said individual. Eventually. Unless it get losts, which happens.
Wind-up Walker: A camel made of cogs, gears and brass. It's very shiny. Please be kind, rewind.
