Just curious on how to defend against this, as my players have done this a few times against me now...

But, the reading of Dispel Magic means that the caster of "Dispel Magic" can dispel each and every spell effect on somebody -

Targeted Dispel: One object, creature, or spell is the target of the dispel magic spell. You make a dispel check (1d20 + your caster level, maximum +10) against the spell or against each ongoing spell currently in effect on the object or creature. The DC for this dispel check is 11 + the spell’s caster level. If you succeed on a particular check, that spell is dispelled; if you fail, that spell remains in effect.

- so, if a level 11 psion casts dispel magic (we use magic & psionics interchangeably) against a prepared level 14 mage with 6 or 7 spells prepared and in effect on himself (say, Shield, Mage Armor, Fox's Cunning, Globe of Invulnerability, Contingency, Greater Invisibility, and Stone Skin),it would be level 11 psion casts his Dispel Magic, and each and every spell effect is d20+10 vs DC25. And, he can then burn extra power points to bump that up to d20+20, basically giving him a 75% chance to dispel each and every effect.

That seems awfully powerful here, and I want to make sure the players are not taking advantage of me here. Should it not just target one spell effect?
