Magic A Is Magic A: Difference between revisions

* Magic in ''[[Rivers of London]]'', at least the type practised by human wizards, appears to be exceptionally rules based and its apparent violation of the laws of thermodynamics greatly worries apprentice Peter Grant.

** {{spoiler|But Beverley Brook, a minor river goddess, seems to do magic in an instinctive fashion.}}

* Magic in the [[Inheritance Cycle]] is limited by several strict rules that are generally obeyed as the series goes on, the most important of which is that magic always [[Cast from Hit Points|drains the mage who uses it]], and the bigger the magic, the more [[Life Energy]] is required.

** Magic in general seems to work off of Newtonian physics. Throwing a small pebble at a certain speed requires as much energy as if you did it by hand. Then you have to consider how far away the target you're enchanting is and even the very ''wording'' you're using in the ancient language, all of which can determine how much energy you could spend on a task. This law can get abstract when you're dealing with metaphysical concepts like turning invisible, healing wounds ranging from cuts and bruises to broken bones and birth defects, and amalgamating enough particles of pure gold to be the size of your fist, to the point that experimenting with magic is extremely dangerous because you don't know exactly how much energy it will require, and very well might kill you.
