Oh, so you want an Iron Caster build.

That's not too hard. It just takes like two-three multiclasses, a specific pair of feats and comes online at like level 6. 

Don't think it comes with Arcane Strike, but tbh you could just scalp one of the Fighter archetypes that give arcane casting/strike to get the Arcane Strike feat as long as it doesn't cuck you out of the required class feature to pull the build off.
