In addition, this is a magic world where the body can achieve sainthood; those powerful warriors tearing apart iron golems with bare hands is not something unusual.
Coupled with the prevalence of healing magic and resurrection magic, the death of those powerful warriors can be easily resolved with a resurrection spell.
However, if a powerful golem is damaged, it can only be repaired by a professional using costly alchemy materials. Once destroyed, you can only recycle the materials and forge it anew.
Moreover, those spellcasters usually have their own alternatives. Take the Laiserman Witch for example; they prefer to summon those elements from the Inner Plane, whose strength is not inferior to most golems.
The most important thing is that they don't need maintenance under normal circumstances, and even if they are damaged in battle, as long as they are not Elemental Lords, you can summon as many as you want based on your own strength.
