'''Background magic''' is the amount of magical energy present in a room, measured in '''thaums'''.
+
 
+
__TOC__
+
==Thaums==
+
A thaum is a unit of [[Magic|magic]], and a large majority of magical practises will leak thaums into the background magic of a room:
+
 
+
* Spellcasting - casting spells will generate thaums equal to 1/5 the size of the spell (in units of [[Head space|mind space]]).
+
* Recharging - [[Recharge|recharging]] an artifact will generate thaums equal to 1/5 of the [[Guild Points]] used (even if no charges are added to the artifact).
+
 
+
The level of background magic decreases exponentially over time, i.e. the more thaums present in the room, the faster they will degenerate.
+
 
+
==Effects==
+
High levels of background magic is known to increase spell power. Other minor effects included increased difficulty to scry the room and increased chances of the room being the anchor for a [[Jogloran's Portal of Cheaper Travel#Failures|misportal]].
+
 
+
Extremely high levels of background magic also make it dangerous to cast spells in the room. Rooms containing over 1000 thaums above normal have been known to break or remove limbs on spellcasting, and cause damage or even death in some cases.
+
 
+
==Levels of background magic==
+
[[Witches' Guild|Witches]] and [[Wizards' Guild|Wizards]] can see an approximation of the background magic level in the verbose description of the room, and anyone can get a more precise reading by using a thaumometer. The various levels are:
