Psionic creatures can operate together to increase the range of psionic disciplines where range is a factor and such increase is otherwise possible.
Where applicable, the multiple individuals link their minds and this then adds a cumulative 50% to the range of the discipline,
so that 2 individuals operating together have 200% of the range normally possible.
However, range base is always that of the weakest individual in the group.
It is possible for 2 or more creatures to operate to increase psionic combat powers.
Such operation must be in "series",
with the additional creatures adding 20% of their total strength (all fractions rounded up)
to the next individual in the chain.

Example: Creature A has 100 points of strength, so 20 points-pre transferred to creature B to bring its total to 140,
and B then transfers 28 points to creature C whose base strength is 130 points but now has 158 points,
and C passes 158 X .20, or 32 points to creature D. All series should feed from weakest to strongest.
Only the final link in the series can attack or be attacked but all creatures in the series will be affected by whatever happens to the final link individual. The final creature attacks and defends for all in the series link.
 

Q: During multiple psionic operations, when two or more psionic
characters are transferring strength points back and forth,
how are the points distributed after the operation is ended?

A: The points that were transferred in series among the psionic
characters are all dissipated and lost to all characters, but may be
recovered in time. It is possible for a character to be left with no
psionic strength points after an operation of this sort, but that
strength can be regained in the usual manner.
