When the Harry Potter series burst onto the fantasy scene like an exploding phoenix, the nature of wands was redefined. Perhaps some other more knowledgable person can correct me, but I don’t recall any fantasy literature delving into wands with such detail, making them quasi-sentient objects with a varying inner magical core.
The wands of Corporia also don’t follow the trend of Harry Potter, at least in regards to the quasi-sentience and core. The type of material does matter, though. Some materials affect specific magical disciplines (such as hornbeam wands doubling the range of Charm spells), while others affect all disciplines but on a smaller scale (such as rowan increasing the range of any Charm, Elemental, Perception, or Spiritism spell by a flat +10 feet]).
Another change is that characters who study the Wizardry disciplines need to use wooden wands, while sorcerers (who, naturally, study the Sorcery disciplines) can only use plastic or metallic wands.
Here’s a quote taken from the “Expenses” chapter (weapons, armor, augmentations, gear, wands), that you might enjoy. Much of this chapter is written and designed like a new magazine tailored specifically to this new demographic of reincarnated knights, awakened sorcerers, and their allies, with editorial, features, product reviews, and such.
“Just as knights use a blade to strike down a foe, so do spellcasters use their wand – a thin, mostly straight stick roughly 12 to 16 inches long.
If you’re a witch or wizard in the market for a new wand, you’ll need a wooden one to focus your arcane powers. Sorcerers, on the other hand, can only benefit from wands composed of metals, plastics, or other artificial materials. (We’ll continue testing to see what other types of wood and materials can be turned into wands.)
Regardless of their composition, all wands can channel a ray of magical energy against a foe for a damaging melee or ranged attack. This ray deals damage equal to the caster’s MGK, and has a maximum range (in feet) equal to the caster’s MGK x5. For example, a caster with MGK 4 may fire a ray dealing 4 points of damage against a target up to 20 feet away.
Wands made of wood, plastic, or other materials have their own unique affinity for magic and may modify spells cast through them. Most of these wands only modify certain spell disciplines, like the cypress wand that doubles the range of Charm spells, or the polypropylene wand that doubles the duration of Holographic spells. Our tests also reveal that some wand materials affect all spells, though you may sacrifice some power for the sake of flexibility.”
