The Generals of Hell Have Taken Notice of You
From: High Command
To: All Military Forces
Subject: Spellcasters Interfering with Plans
Priority: Urgent!
In response to reports from underlings about adventurer's with, dare I say, fiendish effectiveness against our scouts and sorties, we are forced to take extreme measures. Lesser demons in need of disciplinary action and captured mages will now be forced to undergo a procedure that turns them into living Antimagic totems. Supplies of these totems will be limited by our supplies and ability to produce them, but creative placement should make them somewhat effective.

There are also other spells that fiends and spellcasting undead might use to counter spellcasters, such as Silence and Counterspell. However, be careful not to overdo it. Part of the fun of D&D is to stomp through some encounters because of build choices you made, and you definitely don't want to completely shut down a PC's ability to contribute to a fight.
