Q239) What ways are there to pick up a symbiont other than tracking down the nasty beastie? I know there's impure prince, but what else?
-239) I've often wondered this myself. There's a spell in
Lords of Madness that could help:
detect aberration. Also, the organizations dedicated to hunting aberrations would probably have some info on where the beasties lair. You can use
detect undead to help track down the couple undead symbionts that exist. It might be possible to
summon and/or use
planar binding to call some of the outsiders, and you could almost certainly
wish for one, following the rules for "symbionts as treasure" in
Magic of Eberron.
Mostly, I imagine you invest as many skill ranks as you can in skills like Knowledge (arcana), (dungeoneering), and (the planes) as you can, and try to get a reasonable DM who's willing to work with you to get the symbiont you want. Happy hunting!
