I see in "Passive" you have orbiting orbs and Aura. What about that thing, whatever it's called, such as is common in sports video games, where a circle or moving image or something shows up under your feet? A "Floor Aura" vs a "Surrounding Aura", or something. I can't remember what it's called. Anyways, it also shows up in other games (some of the ones I'm talking about might be folded into Circles/Runes).
Such as this:
Some elements, possibly.
Cornstarch (Probably simple uncommon/mundane) - a grainy yellow powder. Useful in cooking, and easy to burn (though no more dangerous than burning, say, wood). It's most interesting properties are those exhibited when mixed with liquid, as it becomes an oozy not-quite-liquid-not-quite-solid substance. On it's own it comes in small piles of powder.
Brass/Bronze or Tin (for mixing with copper) (What's a trumpet if it's made of some useless gold?)
Hill Billy (Complex, similar to Victorian or Bushido in that it represents an... exaggerated culture)
Folded Space (RARE, possibly dangerous) - Pokeballs, Bags of Holding, the TARDIS; All have something in common. They are bigger on the inside than the outside. Without a container or something to fit into, it feels like everything grows larger and/or you have shrunk when you step into a folded space, but it unfolds and dissipates rapidly. Blended with other materials, it causes them to weigh far more, be far more effective or ineffective, and/or expand rapidly, as it packs far more of those materials into the space it would normally occupy. Violently reacts when blended with several possible materials, due to their natures.
Complex Shapes:
Interlocking Bricks
Briefcase (Container with Handle)
Instruments (Trumpet, Lute, Trombone, Piano, Tuba, Calliope, Saxophone, Organ, Flute, etc)
Drill
