I think he wanted moves that raise defense and special defense at the same time.

---

Well in that case thats already there ;) the moves that raise both stats have a * next to them, so that would be stockpile and accupreassure, though i think accupreassure doesnt raise at the same time just random stats.

---

They have missed some though so i will add more.

Thanks a lot :)

Answer 2

cosmic power and stockpile are the only moves that raise def and s.def at the same time, exept for silver wind, ominous wind, and anceintpower if your lucky.
