Mass Combat System

==Battalion Mechanics==
During Mass Combat, each major NPC will be attributed a “Battalion” of creatures. All creatures following them are grouped as a singular entity known as a battalion and the major NPC will be known as a Commander.
For PCs, each Commander role will be filled by two PCs meaning the entire party rules over Three Bataillions that act on their Commander’s turns. The duo of PCs that command one such Battalion both roll Initiative and both take their turn on the highest Initiative roll obtained between the two. On their turn, they can take a “Battalion Action” using the HP, AC and attacks of their units before or after taking their own turns but not in between or during.
==Battalion Statistics==
For statistics, a Battalion uses the base creature that forms the Battalion's HP multiplied by the number of units in that Battalion. They use the base creature’s AC and attacks.
When attacking another Battalion, for a singular Attack Roll, you roll as many damage iterations as you have units.
When attacking a Commander, for a singular Attack Roll, you roll as many damage iterations as you have quarters of your total Battalion HP. Therefore, if you had a Battalion with 100 HP that used a scimitar attack for 1d8 + 2, you’d roll 4d8 + 8 at 100 HP, 3d8 + 6 at 75 HP, 2d8 + 4 at 50 HP and 1d8 + 2 at 25 HP and below.
==Battalion Actions==
Move - The Battalion moves using the base creature’s movement speed.
Hustle - Using its entire turn, the Battalion hustles and moves twice its speed.
Defend - The Battalion is assigned to protect a creature or location. Creatures attacking a defending Battalion or the defended objective do so at Disadvantage. The Commander can also choose to have the Battalion take damage instead of that objective in which case it suffers a Critical Hit, overruling the normal defense Disadvantage.
Retreat - The Battalion uses its entire turn to run away without provoking Attacks of Opportunity. It loses 10% of its HP while doing so while they are adjacent to an enemy Battalion.
Attack - The Battalion attacks using the rules stipulated in the statistics section.
==Battalion Effects==
Buffs/Heals - AoE Buffs and Heals that cover the entire span of a Battalion apply. Single target and other Buffs/Heals do not and should be reserved for Commanders.
Area of Effects – AoE's that affect a Battalion’s entire area apply the damage iteratively for each unit in the Battalion. If it covers only half, then it deals half of the damage, if it only covers a quarter then it deals a quarter of the damage. The Battalion still gets a Dexterity Saving Throw for half damage.
