[OOC][Brainstorming] Intelligent Devices for non-"Lyrical Nanoha" mages

[robkelk]

As I understand it, the average Midchildan or Belkan Intelligent Device (and the above-average ones like Raising Heart, Bardiche, and Graf Eisen) assist their masters by casting minor spells (usually but not always defensive) by drawing upon their masters' magical power reserves, and help with their masters' mathematical calculations for the really big spells. I don't know how much help the Sailor Senshi, or Sakura and Shaoran, or the Fate/Stay Night mages, or the Madoka Magica girls would get from that sort of device, since their magic doesn't appear to have a mathematical component. (Also, Ami already has the Mercury Computer.)

Okay, I got at least part of that wrong. Quoting from All The Tropes: "Some of the math questions that appear on the board in Puella Magi Madoka Magica for an eighth grade math class are taken from, among other places, the entrance exam for Tokyo University. More information here." So at least these magical girls can use an Intelligent Device... even if only to help with their homework.
