If we were to liken the connection devices of a natural Heart of the Magic Puppet and an artificial one to plants.
The former would be wild plants, resilient enough to grow even on cliffs despite harsh conditions, needing just a bit of water to survive.
The latter would be like greenhouse flowers, which wither if neglected, overwatered, or fertilized improperly, displaying their withering immediately.
The natural Heart of the Magic Puppet operates similarly; you can casually draw runes, and as long as you can extract, I'll give you 100% performance, provided you can use it.
The artificial Heart of the Magic Puppet is like a delicate little princess; the connection device can't be too weak or too forceful, or it will faint on you.
Once the Heart of the Magic Puppet is created, its performance is set, but whether you can utilize 100% of it depends on the performance of the connection device.
