Second Round
At the begining of the second round, Initiative is rolled. Apologies for poor rolls, people, but here it is. The manticore is no longer flat-footed.
Manticore 17
Horsom 11+4 = 15
Glom 9+3 = 11
Dain 9+1 = 10
Selanil 1+4 = 5
Kregor 4+0 = 4
The manticore screeched with anger and pain at its rude awakening. Because it had been asleep during the first assault, it had yet to notice the characters further up the hillside. It focused all of its rage on the three before it.
It stepped back (5-foot step) and with a snap of its tail, it loosed a volley of six bony spikes from the deadly cluster in its tail. These flew the short distance toward Selanil, the only of its foes it could see that immediately threatened him. (Selanil's AC is 18, but four of the six spikes hit him for a total of 25 points of damage.) The elf could barely stand after the deadly barrage. (Unfortunately, the Spear of Gwertheyrn ap Nudd is not a reach weapon, so there is no AoO for the manticore's attack.)
Having made its attack, the manticore paused to scan its surroundings, and noted at least some of those on the hillside. "You will all die for this assault!" it sang out, its voice like deadly music. Then it backed off, fleeing toward the eastern slope.
With the manticore's flight, Horsom had to move down slope simply to keep the same range. He fired off two more arrows (3+7 = 10, a miss, and 11+7 = 18, a hit for 11 points). The manticore stumbled as it was hit.
Glom, too, had to move to remain in the same range. "Heh! Fry creature! Glom FRY!" the goblin cried out, voice shrill, as the sound of crackling energy once more filled the air. This time, however, the manticore avoided the worst of the blast (only 7 damage, successful Ref save for 1/2, or 3 damage). Still, the cool breeze blew the scent of singed fur toward the party. On the hillside, Glom laughed.
Dain cursed as he rose to his feet. He raised his shield and came up to where Selanil stood, injured, Tor-Angol readied to smite the fleeing beast. "Taste my cold iron, kitty," Dain yelled. "Your father was a hamster and your mother smelled of elderberries." (Rising from prone requires a move action, precluding a charge this round.)
Although severly wounded by the tail spikes, Selanil gripped the spear firmly. "Do not fail me," he said. He could see that the beast was now barely moving. Its wounds were bleeding freely, both those it had taken this day and those from Horsom's arrows at the mill. It had begun to shake its head as it moved, as though no longer certain of its balance. Kregor was rising behind him, and Dain was steady at his side with his massive war hammer. The spear felt good in his hand, and, despite his injuries, Selanil found new strength in his anger, and charged.
8+6 (melee bonus) +2 (charge bonus) = 16, which is enough to hit the manticore, so there is no indication whether or not the spear also grants a melee bonus. The weapon does a base 6 ponts of damage, +3 for Selanil's Strength bonus. There is no clear indication whether or not the spear does anything special in and of itself, as this is adequate to the task.
Having taken 18 points of damage last night, 27 points in the first round of this fight, and 23 points (or more if spear is magical) of damage this round, the creature is dead.
The Spear of Gwertheyrn ap Nudd pierced the creature through the back, between its still-folded bat-like wings, through crimson fur and deep into the heart. With a last pained scream, the manticore fell to the ground. Its paws twitched feebly, then grew still.
