You realize that one of your latent psychic wild talents is that of a stormlord.

Combat, Outside during Storm

 As you battle, something seems to rise up from within you, and suddenly  
 as if by instinct you find yourself focusing your mind as if to call a   
 bolt of lightning down from the sky upon Eternaleye -- and somehow you can
 feel exactly that happening!

Suffering Electrical Damage

As you are assailed by lightning energies, something stirs strangely within
you, and you realize that you are somehow able to disperse and nullify the 
energy before it can harm you.

Help File

   Stormlords are psychics so-called for their fearsome power of manipulating
 the energies of lightning.  While they cannot create electrical energy out of
 whole cloth, this generally proves little impediment to them.

   The backbone of your powers is the ability to create a field of psychic
 force that absorbs and collects electrical energy.  The power stored in your
 lightning absorption field may then be put to work in other ways.  The amount
 of energy that the field can hold is limited by your level of ability, which
 is determined by your willpower, intelligence, perception, luck, and skill at
 psycholeptesis and metasenses.  The field will attempt to disperse what energy
 it cannot absorb, but its power to absorb and its power to disperse can both
 be overwhelmed by too much incoming energy at once.  Nonetheless, it is quite
 difficult indeed to harm a stormlord with electricity.  You can obtain a
 general idea of how much energy is bound up in your field simply by examining
 yourself; any significant amount of energy will be visible as an aura around
 you.  When your field has a great deal of energy in it, individuals attacking
 you bare-handed or using weapons of conductive material are likely to trigger
 an electrical discharge; be cautious, as this can deplete the strength of your
 field.  To bring up your lightning absorption field, concentrate on absorbing
 lightning; to shut it down, concentrate on ceasing to absorb lightning.  Any
 power stored in your field when you shut it down will be lost.

   You can put the lightnings stored in your field to work by creating small
 lightning arcs to shock opponents.  This ability will draw on the energy stored
 in your lightning absorption field unless you are in circumstances where you
 could call a lightning bolt, as described below, in which case you will draw
 the necessary energy from your environment.  To throw a lightning arc at an
 enemy, concentrate on directing lightning at your target; you may refer simply
 to "my opponent" to target whomever you are fighting.  Your level of ability
 at this is determined by your willpower, intelligence, perception, luck, and
 skill at psycholeptesis.

   The most feared of the stormlord's capabilities is what earns them their
 name: the ability to call lightning down from the sky against their foes.  In
 order to do this, you must be outdoors and the weather must be in such a state
 as to at least hint at a storm; that is, a cloudy sky and a significant amount
 of precipitation.  Your proficiency at calling lightning is a matter of your
 willpower, intelligence, perception, luck, and skill at psycholeptesis; to do
 this, concentrate on calling lightning down upon your target.
