Previously, in Round 2
Ducane runs to the base of the structure.
Round 3
Iggy, standing his ground at the base of the tunnel, blasts magic missiles at one of the Githyanki crossbowmen, dealing 11 damage. He continues to full defend.
Zack (NPC'd) joins Planus and hacks at the door, trying to smash it into kindling with his Scythe.
Zack v. Door (with full PA) (1d20+4=13, 2d4+16=19) The door has 6 of 20 hp remaining.
[Ducane goes here.]
T'Zeran reorients and moves to the doorway, pointing his crossbow inside and preparing to fire upon the door being opened.
The Githyanki crossbowmen continue to fire at Iggy, reloading in frustration as they miss.
1d20+5=14, 1d8=8, 1d20+5=11, 1d8=7, 1d20+5=12, 1d8=7
Two of the Githyanki Swordsmen remain on the defensive, while the third prepares to attack once the door is opened.
[Planus goes here.]
Opale casts a glitterdust at the Githyanki, managing to place her spell's center just inside the central arrow slit. The glittering dust covers the three crossbowmen.
Glitterdust Saves (1d20+1=12, 1d20+1=17, 1d20+1=3) The flash of sparkling dust blinds two of them, though the one injured by the magic missiles manages to squeeze shut his eyes just in time.
Charlarn yells "The ones in the building are a bigger threat than the dwarves." He runs to the base of the building, and will need to reorient in order to get to the door... unless he wishes to attempt a difficult climb check instead. Does he wish to open the door by trying the knob, smashing it, or trying to burst it open with shere strength?
The Dwarves are falling back, apparently content to stay out of the fight.
