3d Boss Battles Script Pastebin | Undertale

Sans is the most requested boss battle. His unique poison damage (Karma) requires a coroutine that ticks damage down over time, even after the bone has passed. A script missing the IEnumerator KarmaDamage() function is incomplete.

Since "Undertale 3D Boss Battles" is a game heavily reliant on timing, dodging, and mechanics, the most "useful" features players look for are Kill Auras (to skip grinding phases) and No Clip (to avoid buggy geometry or hard attacks).

This is a standard, reliable script often found on Pastebin-style repositories. It uses a simple "Kill Aura" function that damages the nearest enemy boss.

Script Code:

-- Undertale 3D Boss Battles Utility
-- Features: Auto Attack, WalkSpeed Modifier
-- Note: Execute with a reliable executor (Synapse, Krnl, Script-Ware, etc.)
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local HRP = Character:WaitForChild("HumanoidRootPart") Undertale 3d Boss Battles Script Pastebin
-- Configuration
local Damage = 50 -- Change this to increase damage per tick
local Toggle = true -- Set to false to stop
-- Function: Find Nearest Boss/Mob
local function getNearestTarget()
local nearest = nil
local minDist = math.huge
for _, v in pairs(workspace:GetDescendants()) do
    if v:IsA("Model") and v ~= Character then
        local hum = v:FindFirstChild("Humanoid")
        local root = v:FindFirstChild("HumanoidRootPart") or v:FindFirstChild("Torso")
        if hum and hum.Health > 0 and root then
            local dist = (root.Position - HRP.Position).Magnitude
            if dist < minDist then
                nearest = v
                minDist = dist
            end
        end
    end
end
return nearest

end
-- Main Loop
spawn(function()
while wait(0.5) do
if Toggle then
local target = getNearestTarget()
if target then
local targetHum = target:FindFirstChild("Humanoid")
-- Simulates damage (works in games without strict server checks)
-- For games with strict checks, this usually requires a RemoteSpy method.
targetHum:TakeDamage(Damage)
end
end
end
end) Sans is the most requested boss battle
-- Speed Hack (Dodge faster)
if Character:FindFirstChild("Humanoid") then
Character.Humanoid.WalkSpeed = 50 -- Default is usually 16
end
print("Undertale Script Loaded. Speed: 50, AutoAttack: Active.")
