Perhaps one of the longer passages in the Old testament about God sending
confusion into the ranks (perhaps several verses from Gideon's rather one
sided battle Judges 7:17-25 - of course, the word "confusion" is not in
that passage...) could be made into a team rune that could only be used
once per adventure and only if the team was outnumbered by at least 3 to
1, and only if they were "On track" with the adventure (In God's Will). 
The result would be utter confusion in the ranks where the dark creatures
saw everyone as the enemy, even their own forces.  

A different example of an application would be usable once per gaming
session, could cause momentary confusion, causing the dark creatures to
hesitate, missing one attack round.  A good passage for that might be
when Moses raised his hand, the Israelites were winning, and when his
hands were lowered, they started to loose.  (Exodus 17:10-16 - or just
verse 11) Again, the criteria for that would be that the light raiders
were outnumbered...and perhaps that Light raider would be required to
raise his hands for that round (missing out on his/her attack along with
the dark creatures.

Is there a word rune for making the enemy completely oblivious to what
you are doing?  Remember when the Angel lead Peter out of prison?  He had
been shackled to 2 guards, and there was a watch outside his cell (a
total of 16 assigned to guard him specifically.  Acts 12).  He thought he
was dreaming until the Angel left him.  That would be perfect for getting
out of an dark creature stronghold after a failed rescue attempt.

Different forms of Confusion - 2 for combat, one for escape.  Just don't
ask me to write the adventure for them  :)
