Does the Blessing of the Forge ability by a Forge Cleric affect the Integrated Protection of a Warforged? My initial thought is no but I thought I would ask…love me some Warforged!!! By RAW probably not. In third edition warforged bodies could be enchanted like armor; in the current model, adding Proficiency bonus to AC is supposed to reflect evolving enchantment, so you can't enhance on top of that.

But things like Fighting Style and Soul of the Forge would apply to a Warforged, correct? It depends on the wording. By RAW, a warforged using Heavy Plating or Composite Plating is considered to be wearing armor, but not a specific TYPE of armor; IE heavy plating doesn't count as heavy armor (though I'd like to see that adjusted).

But if we go with the Warforge from Eberron: the last war Integrated Protection is the donning of armor onto the warforge’s body. They don’t use Heavy Plating or Composite Plating, so Blessing of the Forge ability should work with the new warforge.
