Trying to Decide the Caster Level to make a Holy Symbol Magical sorta like in 4E.
Thinking a Holy Symbol that Adds either +1 per Die in Channeling or Adds Level to the channel for a Stronger Version. Not sure what the caster Level would be per say. Thinking Heal would be the spell Needed... CL 11? Wondrous Item? Might be a lil cheaper then the book suggests, for something like it cause only clerics of that specific faith could use it?
Check out the requirements for the Phylactries of (Negative/Positive) Channeling. And there is a cost break for 'required alignment/ethos' built into the item creation rules.
