Say, for the purpose of example, a party of low level adventurers rounds a corner and meets a group of goblins. Kleegon the dwarven fighter acts first and charges with his battle axe.
Here's how I might run such an encounter.
The Party:
Kleegon the Dwarven Fighter 3 (battle axe, plate mail)
Garin Dell, Dwarven Fighter 1(hvy. crossbow, hammer, plate mail)
Aquel of the Hills, Human Fighter 2 (spear, short sword, mail + shield)
Yod the Calvous, Human Magic User 2 (dagger)
Arius, Servant of the Secret Fane, Human Cleric 1 (mace, plate mail)
The two dwarves are up front, Aquel and Yod in the second rank, and Arius is bringing up the rear.
The Goblins:
A patrol of six goblins with spears and short swords, in leather armor.
Surprise:
No one is surprised.
Distance:
The groups are 80' apart in a 10' wide passage that is lit by torches in brackets on the walls.
Initiative:
Party rolls 6, Goblins rolls 2.
Party has the initiative.
I always ask for actions at this point, with the winning side declaring their intended actions last. Since the goblins lost initiative, the DM says their action is to form up to receive a possible charge, and issue a challenge.
The players declare their intended actions:
Party Actions:
- Kleegon will charge. He's wearing plate mail, so his charging movement rate is 120' -- he can reach the goblins this round.
- Garin Dell will fire his crossbow.
- Aquel will charge, throwing his spear when he gets close enough. He's wearing mail, so his charging movement rate indoors is 180' -- he can reach the goblins.
- Yod will advance to get within range of his sleep spell, but does not want to enter melee engagement.
- Arius will advance beside Yod.
- Garin Dell says that after he fires his crossbow he will move up with Arius and Yod.
DM adjudication:
The goblin patrol's excited challenge to he PCs is lost in the noise of Kleegon's battle cry. Garin Dell fires his crossbow as Kleegon starts running. Garin Dell is 80' away, which is short range for a heavy crossbow. He rolls an 18, which is a hit. The DM randomly determines which goblin is struck: it is Goblin #3, in the front rank, who takes 4 points of damage. Goblin #3 had 5 hp, so he's reduced to 1 hp.
Since both Kleegon and Aquel are charging, initiative does not determine who strikes first: weapon length does. However, Aquel is hurling his spear as he comes, and that will go first. (I allow axes, hammers, spears, and javelins to be hurled during a charge. Similarly, a charged formation may hurl weapons before the charge arrives, but in this case the goblins choose to set their spears, rather than throw them.) Aquel rolls a 19 at his Goblin #2, in the front rank. The spear does 6 points of damage to the goblin's 2 hp; Goblin #2 is skewered and goes down with a cry.
A few moments after the goblin goes down, Aquel and Kleegan smash into their line. Kleegan's axe is shorter than the goblin spears, and Aquel is now using his short sword, so the goblins go first. (Technically, Aquel could reach the line before Kleegan, but we'll assume that he paces the dwarf.)
The DM rules that only the front rank of goblins may use their spears (if the enemies were better disciplined and better trained, the DM might allow first and second ranks to attack with set spears, but the goblins are neither, and just had their formation disrupted, anyway). Since one of the front rank is dead, that's only two attacks. Goblin #1 attacks Aquel, and Goblin #3 attacks Kleegan.
Goblin #1 rolls a 6, which misses (even with the AC penalty for the charge). Goblin #3 rolls a 12, which also fails to hit. The PCs may now attack. Aquel is 2nd level. He gets two attacks against enemies of less than one HD. Kleegan is 3rd level and gets three.
Aquel's rolls are 13 + 2 (from charging) and 13. Kleegan rolls 19 + 2 (from charging), 7, and 3. Both Aquel's attacks hit. His first attack is against Goblin #1, and he does 3 points of damage. Goblin #1 had 3 hp, and goes down to thrust. Aquel's second target is Goblin #6, who takes 4 points of damage to his 4 hit points: he also goes down. Only Kleegan's first attack hits, and he does 3 points of damage to Goblin #3, who was hit by the crossbow, earlier, and only has one point. Goblin #3 goes down, as well.
Yod, Aruis, and Garin Dell have advanced to within 40' of the melee.
The round ends with Aquel and Garin Dell engaged with the two surviving goblins (#s 4 and 5). The DM decides this round has completely broken the morale of the goblins. He rolls a for them, individually, to see if they have the presence of mind to surrender or if they panic and try to flee. The rolls indicate both goblins are panicked and will try to flee.
The DM asks for initiative rolls. The goblins get a 3 and the PCs get a 4. The PCs win, again. The DM announces that the goblins are running.
- Kleegan announces that he will attack the fleeing goblins.
- Aquel announces that he will attack the fleeing goblins.
- Yod was going to cast sleep, but decides not to waste it on two goblins.
- Arius says he will stay beside the magic user, and will be watching for goblin reinforcements, including from behind.
- Garin Dell will start reloading his heavy crossbow.
Aquel gets two free attacks on the fleeing goblins. Kleegan gets three. The attacks are at a +4 to hit the fleeing enemies. Aquel rolls 16 + 4 and 3 + 4. Kleegan rolls 17 + 4, 14 + 4, and 5 + 4. Aquel hits once, and Kleegan twice.
Aquel hits Goblin #5 for 5 points of damage. Kleegan his Goblin #4 for 3 points and 8 points. Both goblins are slain in mid-stride as they seek to flee.
