Tal

The acid breath washes harmlessly over Taliesn. Thanks, Merrick! and he tanks the onslaught of the first dragon's attacks. He responds with a single word: Burn!
Spoiler: Round 2 attacks

Swift action to use his Burning Blade maneuver: +1d6+1/2 IL fire damage to each melee attack (IL is 9, and I don't recall if that rounds up or down)

Move action:
Obligatory jump to trigger landshark boots: Jump - (1d20+41)[57]
Obligatory tumble to avoid any AoO possibly triggered by that jump: tumble - (1d20+26)[27]

Standard action:
claw - (1d20+27)[44] damage - (2d6+16)[20] plus fire - (1d6+4)[8]
claw - (1d20+27)[46] damage - (2d6+16)[24] plus fire - (1d6+4)[5]
claw - (1d20+27)[37] damage - (2d6+16)[22] plus fire - (1d6+4)[9]
claw - (1d20+27)[40] damage - (2d6+16)[27] plus fire - (1d6+4)[10]

* Increase each fire damage +1 if odds round up, if it matters.
* If 2 or more claw attacks hit, damage is doubled, but not the fire damage.
* The previous turn's attack penetrated any DR/magic; current and future attacks penetrate any other sort of DR, thanks to transmutation property of Tal's wyrmfang belt.
* Tal will try to leave the head intact, just in case Merrick is collecting.
