The ogre mage should be CR7 as-is
Isn't the Ogre Mage a CR 8?
It bugs me that somebody brings up a fair point (they are tough in situation X) only to get shouted down with "It's called situation Y, BZZAAP!" It's the opposite of conversation.
I'll be sure to lose some sleep over it.
I guess a better term would be "drive-by optimizer,"... someone who assumes the best possible counter to any given situation will always be available.
Glitterdust isn't the best possible counter to the given situation. It is, however, a counter to the situation that I often see wizards prepare.
Best possible counter is to cast "Summon Mirror Mephit", use its SLA of Simalicrum to create a Solar, and have the Solar beat up the Ogre Mage.
Well, no, that's still not quite as much overkill as possible...
Yes, if your party has access to see invis, fiery burst, glitterdust, orb of fire, eyes of the eagle, and a metamagic rod, then an ogre mage is even less of a challenge than its normally too-high CR would suggest.
Are you confusing me with someone else? I never suggested that the party would have access to reserve feats such as Fiery Burst, and I don't believe I said the wizard would have See Invisibility either. I stuck with Glitterdust and Eyes of the Eagle. A cheap metamagic rod was mentioned as a way to make Glitterdust last longer, but it wasn't critical. I don't believe Orb of Fire was mentioned more than once by myself in a side discussion of how to deal with the Ogre Mage's SR.
Not all players that play wizards memorize what you think are automatic choices. Not even all player that optimize builds do this.
Some people play wizards with an Int score below 10. Some people spend their time learning useless spells like Tenser's Transformation. I choose to assume that the average player is not an idiot and will make reasonable choices.
At 8th level, the spells given above are a fair bit of a wizard's firepower, just for what amounts to an EL6 or EL7 encounter.
Two Glitterdust spells is not a "fair bit" of a wizard's firepower.
Also, Fiery Burst is an at-will reserve feat, Eyes of the Eagle is an wondrous item, and a metamagic rod is a rod, not a spell.
For 4th-5th level characters, where the ogre mage and a single low-CR lackey make a good miniboss encounter, it's wishful thinking.
I do not believe anyone has been talking about 4-5th level characters, at least not recently.
