*nod* Yes, SR is one of the strangest things in implementing monsters... it can either be completely and utterly broken and overpowering, or just a throwaway, almost nothing stat.<br/><br/>Taking out the SR and flight... you've still got the myriad of stat bonuses, and the resistances and immunity (admittedly, not a terribly GOOD immunity, but still...). That +16 stats, overall, which is easily worth 2-3 LA on it's own, and the resists are probably at least another +1, especially coupled with the other minor bonuses.<br/><br/>*ponder* Pick one of the +4's, drop it to 0, and you can have it without LA. That leaves the armor bonus, the natural weapons, the resists/immunity, +12 stats, DR, outsider type (and associated darkvision), all for 2 LA. Maybe not balanced, but closer.
