Interesting, but I wouldn't have that REPLACE dart... Besides, if you want to make it the opposite of secian transfer, then it would have to do double or half of the damage that the psion had taken. If this were installed, it would make a heart cleric a psion's worst enemy. A pair of secians could render this method of attack virtually useless. But without secians or heart clerics present this could make for some very interesting strategy--it would behoove a psion to remain in a state of weak health, which would in turn lead to their death rather rapidly, in all likelihood.

I think it is a very interesting idea, but I do NOT think that it would be a good idea to REPLACE existing abilities/attacks with this one. I'd say, make this one sort of a bonus--make it do half the damage that's been taken and give it a short delay.

I have always wondered if a secian, when confronting a muat, for an example of something that might enrage a secian enough to put them in a violent frame of mind, might figure out by accident how to reverse their empathy and heal themselves by damaging their opponent. It would make for some interesting RP, and I don't think it would be any more likely to be abused than the attack spells and abilities that secians are already given. It would just be like any other kind of attack, only allowed against the same targets Secians already are allowed to attack: undead, non-sentients and Muatana-al.
