If it has reconstruct roll a Warforged!
Maybe the only exeption is PM, since you dont get so much (immunities doubles, and self healing is already here).
Otherwise WF makes easiest to play arcanes (including Artificers). Even if you are .5 or 1 DC behind humand you should be able to bring it high enought to work. The other good idea may be 2hf FvS, the only fvs which gate 2h free.
