Cold Skills vs. Mephisto Can someone tell me why my Frozen Orb is so much more effective against Nightmare Meph than Blizzard? I thought Blizzard was supposed to "own" Mephisto. I have FO at level 5 and Blizzard at level 8, and I find that Blizzard does NOTHING against Meph. I'm forced to use FO. What's going on here?? Thanks.
