A psionicist with this science can affect the way in
which gravity affects an item. The weight of the
item can be increased to 200% normal or reduced
to 25% normal. The effect remains as long as the
psionicist maintains the power. Creatures that are
burdened by extra-heavy armor suffer a
disadvantage to attack rolls and are reduced to ½
of their normal movement speed.
Weapons that are made heavier or lightened incur
disadvantage on attack roll.
Light objects can be thrown or fired twice as far as
normal.
Very heavy objects can be lightened to make them
easier to move.
Some objects may be drastically affected by this
power-a roof doubled in weight may collapse its
supports. while a lightened anchor may not hold
any longer. The DM should use his best judgment
in deciding the exact effects of any particular mass
manipulation. The more massive the object the
power is used upon. the more difficult it is to
affect.
You must make a psionic attack (versus its
material’s AC) to see if power can affect the
object. Apply the following power check modifiers
for heavy objects.
