Editing DnD Desert Raiders Campaign Natural Hazards (section)

==== Glare ====
The sun can be extremely dangerous to unprotected eyes, drying and irritating the tissue. Areas of white sand, salt, gypsum, or similarly light-colored material reflect the sun's glare into the eyes even when not looked at directly. Sun glare is doubly dangerous during winter months, when the sun is low on the horizon and thus difficult to avoid looking at.
Characters traveling in such conditions must cover their eyes with a veil, dark lenses, or a similar eye covering. Those whose eyes are unprotected in such conditions are automatically dazzled. Such characters take a -1 penalty on attack rolls, Search checks, and Spot checks. These penalties are doubled for creatures that have light sensitivity (such as drow or orcs). Characters who take the precaution of covering or shielding their eyes automatically eliminate the risk of being dazzled by sun glare and take no penalties.
Glare-induced blindness lasts as long as characters remain in an area of sun glare and for td4 hours thereafter, or for 1 hour thereafter if the character enters a shadowed or enclosed area. The dazzling effect of sun glare can be negated by a remove blindness spell, but an unprotected character still in an area of sun glare immediately becomes dazzled again when the spell's duration expires.
