Divine Crusader bonus domains.

[Tendie]

From how I read it, I would imagine that one could add bonus domains to a divine crusader. At the moment my Divine Crusader will be forced to have the Travel (Seeker of Misty Isle), Oracle (Forget the name of the PrC), and Spider (Fluff Reasons) domains, and will get two more domains in addition.

So I'm wondering: what are the two most useful domains to have? Should I get envy for Wish or Luck for Miracle? Alignment doesn't matter; any domain is acceptable (aside from those double-spell domains from the Spell Compendium).

So yeah, suggestions?

Miracle is better than Wish IIRC. Spell domain is well-loved.

Diabolic domain (Fiendish Codex 2) has the Planar Binding line, and Transformation domain (Races of Eberron) has all the core morphs.

Those two spell lines access pretty much every effect in D&D.

For the rest, a wand of Substitute Domain is pretty slick.
