Support Character

Hello guys!
I am looking into making a character dedicated specifically to supporting a party.

I want to have as many auras as I can, share charges with the party, have as much magic find as possible with culling strike obviously and if possible, not get a heart attack from loud farts(some survivability).
I have a lv 63 shadow and a lv 66 witch with clear skill trees, one of which I can commit to the build.

What I need now is the actual build, preferably a peasant level of cheap as I am quite poor atm.
Thanks in advance! ;)

There are several support builds linked in the witch builds list.

Look up any of the "aurabot" builds in either the Witch or Scion forum. As a basis though, you will need either Solaris Lorica, or, preferably, Shavronne's Wrappings with whichever variant of the aurabot build you go with.
