Artifacts. Do It Yourself. (a tutorial for Academy players)

Regarding the GARGOYLES. I think it's still better to prioritize speed so they can reach the sneaky archers or mages in one turn. Regarding the GOLEMS. You might be right here. It mainly depends on the situation. And the resources depend on the map. And I'm not saying that all units need artifacts; you can put 3 artifacts into one unit and leave another one with none.
