The Phandalin Chronicles

Ungrim barely flinches as one of the arrows pierces his shoulder.
As the dragonborn unleashes her acid breath, the dwarf clasps his axe with both hands and barrels toward the goblin. Shouting a dwarven battle cry, he hacks at its torso with a wide swing of his weapon. Without stopping, Ungrim then attempts to cleave through the other goblin as well.

Movement: 15ft to reach melee range with the goblins

Dex saves - 15, 5, 6

Int save 18

Akra spews acid over the three goblins and one falls dead.  The furthest away goblin that you now see looks healthier and stronger than the other two hears the whisper in his voice but ignores it.  Thalas's bolt flys wide but Bozzlewick has better aim and gets a solid it. Ungrim steps forward and strikes down the closer goblin but isn't close enough to cleave the last goblin that still stood.

The last goblin looks haggard and near death as it tries to get a shot off with its bow at Ungrim but misses (to hit 11)

Ungrim grins as his axe blow fells the goblin. He kicks the creature out of the way and stomps toward the last goblin still standing.
"Pitiful gobbos, not even worthy of a footnote in my saga." As the goblin's arrow whistles a few inches past his crimson crest, the dwarf growls and closes the distance. He swings his greataxe in a downward arc, attempting to finish the creature off.

Movement: 15ft towards the goblin (South square below the goblin so that the others can still target him)
Action: Greataxe attack on the last goblin - Attack: 16 Damage: 5

Thalas fires another bolt towards the last goblin Attack: 19 Damage: 5

The goblin ducks out of the way of the dwarfs axe and a moment later is pierced by a bolt from Thalas's crossbow felling him.

The goblin is dead. Combat over.
