Gond's Way: Artificers of the Realms

Outside of Arcane Power I cannot remember the last time artificers saw some decent support. At this point despite my fondness for Neverwinter I would still not say that I am an overall fan, but almost all of the flavor content can serve as a foundation for other campaigns despite all the Realm's references; for example instead of Gond you could substitute Moradin or Ioun, and the Lantan Scholar background can just be renamed to whatever lost civilization you want. I do like the idea of tying the artificer to a divine organization, if for no other reason than I have been playing Space Marine and it makes me think of techpriests.

There is also seven spells and two feats for the crunch fans:

• Ice Shard Traps (level 1 encounter): You create two invisible traps on the ground that deal cold damage and both cold vulnerability and combat advantage for a turn after an enemy steps on one. The downside is that they only last for a turn, so they would work best for groups that have forced movement (or you could combo it up with thundering armor or unbalancing force). Depending on your DM, you could use these with as part of a surprise attack against patrolling monsters.
• Shadowy Figurine (level 2 daily): You create a sustainable figurine that grants partial concealment and a Stealth bonus to nearby allies. 
• Smokepowder Detonation (level 5): A ranged attack that deals fire damage and ongoing fire damage. As an effect, an ally can make a basic attack (with an attack bonus from your Con or Wis if the initial attack hit).
• Arc Infusion (level 7): Lightning damage, grants an ally a save with a bonus from your Wisdom, and deals more damage plus a daze if the ally's save actually worked.
• Siphon Fate (level 17): Targets one or two creatures, deals psychic damage and imposes an attack and defense penalty (save ends). As an effect, an ally gains a bonus to attack and defense bonuses based on the number of targets you hit.
• Synchronized Weaponry (level 25): A sustainable effect that allows you and an ally to attack a monster after the other has hit it as an immediate reaction, but both attacks need the weapon keyword.
• Coiled Spring Traps (level 27): Similar to ice shard traps, this gives you three, and they deal force damage, slide and prone, and impose a penalty to AC and Fort based on your Con or Wis for a turn.
• Arcane Trapsmith: Gotta be trained in Thievery, but it lets an artificer use her Intelligence mod to disable traps and open locks. Even better, you gain an Arcana bonus when dealing with traps or hazards.
• Hammer of Gond: You have to worship Gond (but any good DM will handwaive this), and it lets you use a warhammer as an implement (which you can treat as a heavy thrown with a range of 6/12).
