Necronomiconomics
From Dungeons of Dredmor Wiki
"Necronomiconomics: The study of economic principles of the dead, thought from the book bound with strange leather. A shady magic indeed."
Necronomiconomics is a magical skill with incredible power, even at low levels, however, these powers come with great personal costs. Each spell in the Necronomiconomics skill tree has several associated costs or penalties beyond just the mana points spent to cast it. The character casting these spells might take damage, find their stats reduced, lose a large quantity of mana, or all of the above. Because many of these penalties are capable of "stacking" extending the duration of the penalties, great care must be taken not to over-use the spells or the character might find that they are too weak at a critical moment.
These penalties are considered Curses, however, so anything that will remove curses can be used to offset these costs (eg, Zodiacal Wand or Potion of Purity).
The most significant penalty for all of the spells (except Nightmare curse) is 
necromantic damage over time (DOT) to the character. The amounts of said necromantic damage per 'tick' is a consistent value based on the character's own 
magic power. Thus it can be resisted with a corresponding level of 
Necromantic Damage Resistance. For example, a character with 6 magic power only needs 1 Necromantic Damage Resistance to negate all to the himself from any Necronomiconomics spell (see Necropain entry for the full table of Necromantic Damage Resistance values needed).
[edit] Levels
