- New footpad/ninja skill: strike from the shadows. Added all relevant
    helpfiles.

    Keep your eyes open, folks - we'll be developing flanking in a number
    of exciting ways for various classes in the near future! =) Feedback
    and comments to Whim. =)
   
  - Rescue is now a basic heroic feat prevention; certain classes will be
    able to lower that prevention in the future.
  - Redirect is now a basic tactical feat prevention; certain classes will
    be able to lower that prevention in the future.
  - Capturing a Sigil in a Sigil Citadel will now force that player to be
    visible for 30 seconds.
  - The Deacons of Accolades are no longer attackable.
  - Fixed all scripting in Pain's Tabernacle so that invisibility, cloak,
    or similar effects will no longer avoid aggressive mobs, throw off
    the timing of incoming waves, or cause waves to sometimes stack.
  - IMPORTANT! Fixed the Pain's Tabernacle curators who were erroneously
    non-masters; now all curators should be masters.
  - Fixed the Pain's Tabernacle bosses so that they wil no longer fail to
    load salvage in certain unintended situations.
  - Clarified the sixth sense helpfile regarding intellect and wisdom.
  - Clarified the bash, stun, beguile, channeled anger, temple touch,
    foxbat shiv, and petrify helpfiles regarding mastery beyond 100%.

Usage: automatic

Strike from the shadows is primarily an adjunct to the ambush skill. Setting
an ambush requires patience and careful preparation, all for the sake of a
single attack which will necessarily reveal and expose the ambusher (although
hopefully not until the relevant back has been stabbed). A successful shadow
strike, however, will allow the user to utilize the cover of shadows even after
the ambush has been initiated.

Whenever this skill is successful, all of the shadow-striker's attacks will be
treated as flanking attacks for a brief duration after the ambush is sprung -
a powerful offensive benefit. A player who has fully mastered this ability will
find him or herself able to strike from the shadows after every ambush, even if
the ambushing attack itself fails to land.

While the tactical benefit of this skill is great, it also possesses a strong
limitation in its very short duration. The shadow-striker has only a scant few
seconds in which to capitalize on the confusion of the prey. The duration of
the benefit is directly correlated to the user's agility. Note that once the
user has enfolded himself in the shadows, s/he may continue to strike from
concealment for the full duration - even if the original victim is killed.

Finally, strike from the shadows provides an additional benefit to users who
exceed 100% mastery, in the form of a damage bonus to all flanking attacks.
