I thought of the wizard's spell, "Magic Missiles"

Calculatable factors of physics
Large target 3+meters
Medium 2 meters
Small 1 meter or less

Calc 1 "Velocity to target"
Calc 2 "Target direction of travel" (1 toward 2 away 3 equal distance or standing still)

Basic impact damage makes sense to have +/- modifiers based on movement

Magic missiles explode on impact, causing that violent air displacement and whatever magical shrapnel is sent flying. So the concussive exploding damage and the direction of travel and mass of the target should be affected.

-- Function to calculate relative velocity damage multiplier
local function get_velocity_damage_multiplier(target, explosion_pos)
local target_velocity = target:get_velocity() or {x = 0, y = 0, z = 0}
local target_mass = target:get_properties().physical and target:get_properties().collisionbox[4] or 1 -- Estimate mass based on size
local explosion_force = 1.5 -- Base force of explosion impact

local relative_velocity = vector.length(target_velocity)
local direction_factor = vector.dot(vector.subtract(explosion_pos, target:get_pos()), target_velocity)
local damage_multiplier = 1 + (relative_velocity * 0.3)

if direction_factor > 0 then
    damage_multiplier = damage_multiplier * (1 + (target_mass * 0.2))  -- Running towards explosion amplifies damage
else
    damage_multiplier = damage_multiplier * (1 - (target_mass * 0.1))  -- Running away slightly negates damage
end

return math.max(1, damage_multiplier)

end

-- Function to handle magic missile impact explosion
local function magic_missile_explosion(pos, target, base_damage)
if not target then return end

local multiplier = get_velocity_damage_multiplier(target, pos)
local final_damage = base_damage * multiplier

target:punch(nil, 1.0, {damage_groups = {fleshy = final_damage}}, nil)
minetest.chat_send_all("Magic Missile hit! Damage: " .. final_damage)

end

-- Spell: Magic Missiles
local function cast_magic_missiles(caster, target)
local num_missiles = math.random(3, 5)
local base_damage = 5 -- Base damage per missile

for i = 1, num_missiles do
    minetest.after(i * 0.2, function()
        if target and target:get_pos() then
            local impact_pos = target:get_pos()
            magic_missile_explosion(impact_pos, target, base_damage)
        end
    end)
end
