There are very few PrCs that are worth it for Wilder because you miss out on Wild Surge, which is pretty much the only reason to be a Wilder in the first place. Anarchic Initiate advances it, but it's actually harder for Wilders to get into because of the Knowledge (Planes) requirement and doesn't add a great deal to them even then.


My personal favorite PrC for a Wilder is Soul Manifester, which is actually perfect for you since you're already using incarnum and picking up Azure Talent anyway. It doesn't advance Wild Surge either, but it has two strong advantages that make up for it:

1) Soulmelds that can cover for your low Powers Known - For example, instead of burning a feat to learn Psionic Fly, you can just fly with your Airstep Sandals/Pegasus Cloak instead; likewise, instead of learning Defensive Precognition, you can rely on your Incarnate Avatar or Cerulean Helm to boost your AC instead.

2) You can get greatly increased mileage out of your high Charisma with certain soulmelds, most notably Mage's Spectales and Psion's Eyes, which enable you to roll high checks with UMD and UPD respectively. This further lets you cover for low powers known by relying on items like scrolls, stones, staves and dorjes instead. You can also use Silvertongue Mask to be a more effective party face.

You also get access to all the standard incarnum/psionics synergies like Psycarnum Infusion and Midnight Augmentation. Two levels of Incarnate or Totemist will get you into the class and you will still attain 9th-level powers.
