Why only wood is used

Anyone who delves into the craft of wand making will sooner or later encounter the question of why wood is used. The obvious explanation is usually that it's a matter of tradition. Wood is readily available, easy to work with, and has proven its worth over a long period. This quickly leads to the assumption that other materials could serve the same purpose if processed appropriately. This reasoning doesn't hold up in practice. Even the selection of the material reveals a limitation that is often overlooked. Not every type of wood is suitable for a wand. A large portion remains completely unusable, regardless of how carefully it is processed. Only with experience does one recognize which trees are even capable of bearing a core and responding to magical impulses. Not every wood can produce a staff. Most cannot. This shifts the starting point. The question is no longer why wood is used, but why only a small portion of it is suitable. The answer lies in its structure. Suitable woods possess a form of reactivity that can neither be manufactured nor forced. They absorb impulses, modify them slightly, and transmit them. Other woods remain inert. They can be shaped, but show no usable reaction in use.

From this, it becomes clear why other materials are not suitable. What is already lacking in most woods cannot suddenly be found in metal or stone. These materials do not possess a comparable internal structure that responds to magical impulses. They can be worked, but not brought into a state in which they could function as a mediating medium.

Experiments with metal show a particularly clear failure. Contrary to popular belief, it does not amplify impulses, but rather weakens them significantly. What initially appears to be direct transmission turns out to be a loss of structure. The impulse is not carried, but rather flattens out. Subtleties are lost, mountains crumble, and what the magician clearly intended reaches the target only as a rough approximation. For people who rely on a staff to amplify and focus their magic, this is useless. Stone behaves even more unambiguously. It barely reacts to subtle differences in impulse and only absorbs what is applied with considerable force. Even then, the effect remains rigid and limited. A large part of what is present in its initial stages does not reach the level of effect. Therefore, there is no basis for precise or even reliable magic. Organic alternatives are also of no help. While bone or horn possess a natural form, they lack the necessary balance. Their structure reacts unevenly and dampens impulses in unpredictable ways. What passes through loses clarity, while other things completely disintegrate. A consistent reinforcement does not result.

The crucial difference lies in the fact that suitable woods are not merely physical carriers. They actively participate in the transmission. Their structure allows them to receive, hold, and simultaneously amplify an impulse. This amplification does not occur crudely, but in an ordered manner. This is precisely where their value lies.

Other materials do not fulfill this condition. Metal dampens and loses structure instead of carrying it.

Stone blocks and allows only a residue to pass through. Organic alternatives disperse what they absorb. None of these materials is capable of guiding a magician's impulse in such a way as to produce a clear, amplified effect. The fact that only some woods are suitable also demonstrates how narrowly these requirements are defined. Even within a living material, this ability is rare. It is not a question of shape or workmanship, but rather a property that is present or absent. This is repeatedly confirmed in use. A suitable staff absorbs an impulse and returns it amplified, without distorting or losing it. Materials lacking this foundation weaken it or allow it to disintegrate uncontrollably. Nothing can be changed about that afterwards.

The idea that wood is merely one of several possible options arises from an external perspective. It overlooks the fact that a strict selection process already takes place within the wood itself. Only a small portion possesses the necessary properties. Everything else is eliminated.

From there, little room for maneuver remains. If even most woods are unsuitable, there is no reason to assume that other materials could fulfill this role. What they lack cannot be added. And without this foundation, no magic wand can be created.
