Staff Countermeasures

[Shostak]

This creative use of magic came up in a game recently: A relatively humble wizard took away the souped-up wooden staff of a superior enemy mage by maneuvering adjacent to him and hitting it with a Fire spell. It was a dangerous move, but it paid off; the victim, not knowing Destroy Creation, Magic Rainstorm, or Fireproofing, was left without his favored hand weapon and mana reservoir and was thus far more vulnerable to the PCs.

Any other reports of interesting ways to neutralize these arcane toys?
