Such a high level party should have no issue with this beast. Hit him with Breach while your warriors pound. He might have some magic resistance? So maybe start with Lower Resistance or any of the higher level anti-magic spells that include a component to lower resistance.
I solo that punk. Was not easy but some things I noticed that could help you:
-you can leave, heal and come back. He doesnt recast stoneskin or heal while youre out.
-I try to get a good start - example, his stoneskin gone and 2-3 solid hits, then (bleeding like crazy) run away per 1st point, then come back with improved haste charge #2 popped.
-Really important: I think he will hit your fighter on like a 3+. Think kill speed (thaco and damage, types of damage) and saves not ac at all. Double check me on that... watch his attack rolls. Maybe your tank(s) have nutso ac and I'm wrong.
If neither of those points help, I can think of a couple more. Let me know.
