Desert rangers are versed in using the sun as an ally in their hunts. By using careful positioning in combat to keep himself between his foe and the sun, a bedouin can:

(just a few ideas, not meant to all work at the same time or with the same skill)

-enter command to negate a round of combat? (angel's wing with a side of setup a la owaza?)
-be extra dodgy/ripostey? (automatic a la rebounding strike)
-be extra evadey? (automatic skill)
-be extra hard to engage in combat?
-get extra hits?

Works best in desert/full sun. Works less and less with varying degrees of sunshine/cloudiness. Doesn't work at night.

If automatic, it can be a togglable skill - offensive, defensive, and utility settings?
