40 x4 w the elation
Okay, so the first round she gets 30 feet ahead of Wake. He is flying at 45 x2.
I assume then that the tunnel is straight, so she can go 4x speed. I case its needed, Wake has Displacement, Luminous Armor, Overland Flight, Elation, Spell Resistance, Telepathic Bond, Polymorph, Good Hope, and Shield of Faith.
His AC is 42, his SR is 26, he has Imp Evasion. He has low light vision, so he can see pretty far with the armor.
With all this conversation, how many rounds has she been running?
