Damage Type Overrides

Damage Source Overrides allow you to take a pre-existing damage source and augment it to be handled as Alembic damage types.
Example JSON:

{
  "priority": 1,
  "source_overrides": {
    "alembic:alchemical": {"alchemical_damage": 1.0},
    "minecraft:wither": {"arcane_damage": 0.50, "true_damage": 0.50},
    "minecraft:sting": {"alchemical_damage": 0.20, "physical_damage": 0.80},
    "alembic:allergy": {"alchemical_damage": 1.0},
    "minecraft:out_of_world": {"true_damage": 1.0},
    "minecraft:lightning_bolt": {"true_damage": 1.0},
    "minecraft:freeze": {"true_damage": 1.0},
    "minecraft:wither_skull":{"true_damage": 0.10, "arcane_damage": 0.60, "physical_damage": 0.30},
    "minecraft:in_fire": {"fire_damage": 1.0},
    "minecraft:on_fire": {"fire_damage": 1.0},
    "alembic:soul_fire": {"fire_damage":  0.50, "arcane_damage":  0.50},
    "minecraft:player_explosion": {"fire_damage": 0.50, "physical_damage": 0.50},
    "minecraft:explosion": {"fire_damage": 0.50, "physical_damage": 0.50},
    "minecraft:fireworks": {"fire_damage": 0.50, "physical_damage": 0.50},
    "minecraft:fireball": {"fire_damage": 0.70, "physical_damage": 0.30},
    "minecraft:drown": {"true_damage": 1.0},
    "minecraft:magic": {"arcane_damage": 1.0},
    "minecraft:trident": {"arcane_damage": 0.25, "physical_damage": 0.75},
    "minecraft:sonic_boom": {"arcane_damage": 0.50, "physical_damage": 0.50},
    "minecraft:thorns": {"arcane_damage": 1.0},
    "alembic:evoker_fangs": {"arcane_damage": 0.10, "physical_damage": 0.90},
    "alembic:guardian_beam": {"arcane_damage": 1.0},
    "minecraft:mob_attack_no_aggro": {"physical_damage": 1.0},
    "minecraft:mob_attack": {"physical_damage": 1.0},
    "minecraft:player_attack": {"physical_damage": 1.0},
    "minecraft:arrow": {"physical_damage": 1.0},
    "minecraft:thrown": {"physical_damage": 1.0},
    "minecraft:fall": {"true_damage": 1.0}
  }
}

priority works the same as all other Alembic JSONs.
source_overrides contains vanilla damage sources mapped to Alembic damage types and a multiplier. In this example JSON, the alembic:soul_fire damage type, when taken by an entity, deals 50% of its damage as alembic:fire_damage and 50% of its damage as alembic:arcane_damage. When damage is dealt to an entity, the damage type is intercepted and split into each Alembic damage type and dealt again, splitting the amount of damage according to the multiplier.
