Wall: +30%
  You can set up a power or advantage as a line of hexes, affecting
anyone or anything crossing it. This enhancement cannot be applied to
psionic abilities. The wall will be one hex long for every two levels
of power (or points of HT, for advantages), and two hexes high. The
height can be doubled by halving the length, but the length of the
wall can only be extended with the enhancement Wall Length.
  The surface area of the wall can be doubled by halving the
substance of the wall, so that it only does half damage or protects
with half of the DR put into it. This must be decided when the Wall
enhancement is bought, and cannot be changed; a character cannot
create a 6-hex, 10d wall one round and put up a 12-hex, 5d wall the
next. It's one or the other.
  If the power or advantage with this enhancement can only be used as
a wall, and can never be used as a normal power or advantage, the cost
of the Wall enhancement drops to +20%.
  If you buy this enhancement twice, you can form the wall into any
shape you choose, and you can choose whether or not to halve the
substance of the wall (to double the surface area) each time you use
the power.
  The game effects of the wall should be decided when the power is
purchased. If the power has the Instantaneous enhancement, it can be
used as a super-block. Advantages (such as DR) that are to protect
others must have the Affects Others enhancement. The player must
specify (when the Wall enhancement is bought) whether the wall will be
transparent or opaque. If it is transparent, it is not invisible; the
outline of the wall will be visible to everyone unless the No Obvious
Effect enhancement is taken. If it is opaque, the super can not see
through his own wall! To simulate a wall that only the player can see
through, buy the Smoke power with the Wall and Doesn't Harm User
enhancements, and link it to the wall. Firing through an opaque wall
(from either side) is at a -6 penalty (-4 if the wall is only one hex
long).
  
Wall Length: +5%
  Each level of this enhancement adds one hex to the length of a
power with the Wall enhancement.
