whats the necronomiconomics skill good for dungeons of dredmor

Answer 1

It contains a set of incredibly powerful spells that will very easily kill anything you cast them at. However, in counter balance of its highly powerful spells, every time you cast a Necronomiconomics spell, you accrue a Blood Debt.

 

The Blood Debt will deal 2 damage to you every turn for 6 turns. If you continue to cast Necronomiconomics spells, this Blood Debt stacks for each additional spell, and will quickly deal enough damage to kill the caster. It's not advisable to use these spells until you are strong enough to overcome the Blood Debt.

The Blood Debt also decreases your heal rate, extending it by 1 turn. Further, you acquire a non-stacking Lingering Weakness effect which further decreases your heal rate by 1 turn for a very lengthy duration.

It has good synergy with Fleshsmithing, which has a Health buff and a healing spell to help you survive the Blood Debt you acquire.
