Damage <Attribute> M points

Permanently lowers one of the Attributes of the target by M points. Derived attributes such as Fatigue, Health, Magicka, Encumbrance will be recalculated. The attribute can only be restored by use of a Restore Attribute effect.

[edit] Notes

This can be used to permanently stop an NPC or enemy from moving at all by casting a strong enough Damage Strength spell to reduce their Strength to zero, or to the point where their equipment makes them over-encumbered.
You can also cause other effects similar to this, such as making it impossible for an enemy to regain Fatigue by damaging their Endurance, stop spellcasters by damaging Intelligence, cause enemies to miss nearly every time with Damage Agility, and so on.
Damaging Willpower will make enemies more susceptible to spells like Silence and Paralyze.
Damaging Agility makes it more likely that you will knock enemies down to their knees with a strong attack.
Damaging Speed slows the target down, allowing you to make a quick escape from enemies.
Damaging Intelligence makes spellcasters unable to use their spells, similar to Silence.
