 Hm, don't think so.  The only way you can hurt an enemy's MR outside of pushing magic scale is by feebleminding, IIRC, and there's no real mass-feebleminding.  Nether darts can cause feebleminding to those it hits, and there's the Staff of Kurgi 

 and the Black Bow of Botulf for smaller-scale feebleminding.
