Elemental Storm

This is a meta-enhancement – a combination of enhance-
ments and limitations, treated as a single enhancement for
convenience – from GURPS Power-Ups 4: Enhancements.
Once a day, the user may perform a dramatic gesture
(smashing a vessel of water, striking the ground with a staff,
etc.) and initiate a “storm.” The gesture is treated as an Attack
maneuver. The GM may wish to imitate martial-arts films by
requiring the user to call out the name of the attack!
On the attack turn and on each of nine subsequent turns (10
seconds total), the storm blasts everyone, friend or foe, within
16 yards of the spot where he stood. Roll an attack from above
at skill 14; victims may block or dodge, but must focus their
attention either upward on the storm or on foes at ground
level, suffering -2 on defenses vs. attacks from the other direc-
tion. The summoner is safe if he remains at the eye of the
storm, as is any foe in close combat with him, but if he moves
away (or is moved!), he also suffers the storm’s effects. He can-
not end, move, or modify the storm once it begins.
