[Son of Arathorn]

Alright, here's an earlier version, incorporating some of the corrections above, of Cover and Retaliate. It might solve the problem of the attack vs. auto-wound.

If ??? is adjacent to a Ruin, Jungle Piece, Rock Outcrop, or Glacier Mountain, and receives one or more wounds from a non-adjacent attacking figure, roll the 20-sided die. If you roll a 1-?, nothing happens. If you roll a ?-?', ignore any wounds just receives. If you roll a ?'' or higher, ignore any wounds just receives, and inflict one wound on the attacking figure if it is within range of ???

P.S.- ?=number, ?'=number higher than ?, and ?''=number higher than ?'
