Would it be possible to get somekinda skill/spell that allows all psionicist
gain rep in party even tho only one psi seizes the monster in party.

I personally feel its kinda stupid that all psioncist in same party have to
seize the mob to gain rep.
just an idea.
Idea for spell/skill: The spell skill could be named as 'psychic link' or such
and could cost 100-150sps and last for ~20mins. or what ever suits you.
The spell would be casted naturally on fellow psionicist in the same party,
and as penalty, if the spell caster gets psychic damage it would be shared
between linked members, since they are in 'mental connection' with each other.
