Cardcaptor Torika was created by Clowprincess223 (or Nasdreks, as she is apparently more commonly known around here) and I did a fanart of her star character in the illustration style of a giant fanfic that I've been doing, entitled Science and Sorcery. (No, I will never release the entirety of the now-25-season series. But I have been known to dish out snippets.)
Anyway, this wand that Torika uses is called the Terrawand. It sets itself apart from all other Clow-based wands before it because it allows Torika to call on the magical energies of nature itself, boosting the already formidable powers of her Heart Cards, or Terra Cards as they all eventually become. The defect of the Heart Cards was that they weren't capable of fully utilizing all of Torika's magical strength as they were, and thus needed to be "upgraded" in order to give Torika a standing chance of fending off the considerably-higher caliber of opponents that she faces in Science and Sorcery.
For an example of an upgrade from Heart Card to Terra Card, the Terra Card version of Fly gives Torika huge wings on her back, more like Yue's scale than Sakura's, and Torika's wings are also faster and tougher as Terra Cards. For another example, the Terra Card incarnation of the Sword Card turns Sword into a mighty two-handed scimitar, unlike the skinny little fireplace poker it looks like normally.
