Circle

Circling causes a build up of magical energy which increases the background level of magic within the circle. (Background magic is regularly measured in terms of "thaums of energy".) This in turn increases your chances of successfully casting spells and other commands (commonly used for enchanting). The higher the bonus you have in ma.sp.special, the less witchy paraphenalia you will need until you reach the point that you need no occult items to circle.

From Woom: A room void of background enchantment has 0 thaums, and casting spells add 1 thaum per 5 size units. When a circle is traced, and a spell is cast inside (or outside) of it, the background enchantment inside (or outside) the circle will pop up to a background enchantment near your bonus in special. A bonus of 300 will result in a background enchantment of around 300 thaums, etc.

This costs 100gp to perform.

Will need (at an early age): mummified bat, grail, red candle, witches hat, occult jewelery, black and white ceremonial knives, etc. however, as you advance ma.sp.sp you will need less and less of these materials.

Tip: With a 281 bonus I can circle with only my hat on. With a 300 bonus you'll need no occult items at all. "dispel circle" will get rid of a circle.
