Keywords are:  'debuff blinded'

Some spells and skills can temporarily blind an opponent. You can be
blinded by bright lights, dust, or even noxious gas. If you are blinded,
you will have a difficult time perceiving and manipulating your environment
until it wears off.

Blinded enemies are easier to flee from. Being blinded makes it more
difficult to hit with many warrior and thief skills. Ranged attacks such
as throwing weapons and firing arrows are nearly impossible. Most spells
are aimed magically and are not dependent upon sight, so blindness is not
as great an impediment to spellcasters.

The 'sundrinker' spell reduces your chance to be blinded by light-based
attacks, while 'extended sight' spell makes you more susceptible to
these attacks. The 'eyebite' curses makes you easier to blind, while
the cleric 'vision' spell can restore eyesight and protect against
being blinded.

The flaming debuff greatly hampers your ability to resist being blinded.
