Mass Combat - Cry Havoc

Mass Combat rules taken from the Cry Havoc rules. All tables referenced below can be found on the Mass Combat Tables - Cry Havoc page.

Unit Statistics

Units have the statistics of the creature that makes up the unit (for simplicity sake, there will be no mixed units). Units are groups of 10 (so 10, 20, 30, 40, etc.). Units have four additional stats:

Unit Attack Bonus (UAB): BAB + STR Mod + Size (as per the individual creature) + Weapon Damage modifier (see chart) + Misc Modifier. Note that the first three numbers are basically the creature's normal attack modifier. Example: A unit of kobolds with a spear is -1 UAB (Kobold's are +1 with a spear, damage of 1d6-1 is an average of 2.5, rounding down, so they get a weapon modifier of -2). A Hill giant with his greatclub is +18 (+14 normal attack, 2d8+10 damage is average 19, divide by 5 round down is +4).

Unit Ranged Bonus: As above, but use DEX rather than STR

Damage Factors (DF): Creatures have hit points, units have "damage factors". Divide hit points for the individual creature by 5 and then multiple by the # creatures in the unit.

Morale: Hit Dice of the base creature + WIS modifier

Combat

Scale: Mass combat occurs with 50 foot squares. A Unit is the size of the base creature x 10 x the number 10s in the unit. Example: A unit of 50 humans is 5' x 10 x 5 = 250 feet across, or 5x5 squares on the map.

Attacking: When attacking, a unit makes one attack roll for every 10 creatures in the unit. The attack roll is 1d20+UAB compared to the AC of the unit or PC being attacked. You look up that result on the Unit Vs Unit Mass Combat or the Unit Vs PC Mass Combat table. Each hit on that table deals 1 DF to the unit being attacked.

Taking Damage: The damage factors from the table tell you how much damage you take. As a unit takes damage, it gets smaller on the battlefield. Example: A unit of 30 warriors with 10 hit points has 2 DF per creature and 60 total. Every 20 DF reduces the size of the unit by 10 (10 creatures x 2 DF a piece).

Initiative: Each commander makes a Command Roll to determine the initiative order for the battle

Special Rules

Reach only applies to a unit next to you.

No normal AoOs. AoOs occur: When entering melee with a unit that has longer reach. Moving at all when in melee contact with a unit. Units with ranged attack, can take 1 AoO against a unit moving into melee contact with it.

PCs in Mass Combat

A PC can elect to be "in" a unit and takes no mass combat damage (they could still be targeted by an enemy commander). If the unit is destroyed, they are considered on their own.

Alternatively, a PC can elect to be on their own. Remeber that since squares are 50x50, more than 1 PC may be in a mass combat square. If more than one PCs are present, AC is averaged and damage is spread out among them. Individual PCs attack a unit use the PC Vs Unit Mass Combat table. PCs on their own can attack units, commanders,

Commanders

For a PC to be a commander, they must have INT or CHA of 11 and one of: +4 BAB; 5 ranks in Bluff, Intimidate, Diplomay, or Profession (Soldier)

Commanders can give orders to their units that are within 500 feet. Units without commanders or orders attack the nearest enemy unit.

Command Checks: Leaders make command checks in one of three ways: BAB + CHA modifier, Profession (Soldier) check, Diplomacy or Intimidate check at -5.

Some actions in combat require Command Checks:

Move to redezvous point: DC10

Approach Commander ("To Me"): DC5

Become Commander (PC joins a unit and starts giving orders): DC20

Attack Not Closest Unit: DC15

Bolster Attack or Morale (Gives +2 to the unit's attack roll): DC10

Melee Maneuver (Move while in melee contact without an AoO): DC10

Ready Action: DC15

Morale

Check morale when: Unit loses it's commander, when lost half of their damage factors and again when under 1/4 of damage factor.

Morale Check is: 1d20 + Morale bonus. +1 with a commander in the unit.

Morale checks are opposed checks Vs the unit that attacked you.

If you lose the morale check: Retreat 50 feet, provoking an AoO

If winner's morale check is 2x your roll: Retreat 50' and then take a move towards your rear

If winner's morale check is 3x your roll: Unit is routed and flees the battle.
