I'll pick a spot once the group pops up. Gotta stay within 75 feet of everyone to catch them all in Haste.
Initiative: [1d20+27] = 15+27 = 42, [1d20+27] = 4+27 = 31(Due to Ring of Anticipation, I roll twice, and take the better result.)
Default auto-results for knowledge checks:
Knowledge: Arcana [11 + 19] = 30
Knowledge: Dungeoneering [11 + 14] =25
Knowledge: The Planes [11 + 19] = 30
Don't forget everyone, as soon as we roll initiative, everyone can take a free move or non-offensive swift action that can't be reacted to.
Damaros will use this opportunity to double his DR and fast healing for 1 round as a swift action (
Tanar'ri Frontline), since that's honestly the only swift action ability he's got (though he has plenty of immediate actions).
As soon as our round starts and I pop in on the map, Damaros will also activate
Haste on the group as a free action.
