Okay i need some advice:
Either i can have a parasitic character that that can jump inside an ally and add their healths together and boost stats and stuff and can use his abilities through his ally
or
i ccan have a parasitic character that can sit away from the fight, but be almost completely helpless stat-wise and can use its abilities through allies and can transfer health from himself to his ally(but only by physical contact).

It seems, on the second one, physical contact counteracts sitting far off.
