local awesomeprojectileO = game.ServerStorage.Items.SickProjecitle
-- This does not actually exist in the game's code. I assume that
-- I have a cool projectile with ideal traits, such as CanCollide
-- set to false, Anchored set to false, etc., just for example.

function Use(...)
	local args = {...}
	local awesomeprojectile = awesomeprojectileO:Clone()
	awesomeprojectile.Parent = game.Workspace

	awesomeprojectile.CFrame = args[1].CFrame * CFrame.new(0,50,0)
	-- The projectile's position and rotation are set to match that
	-- of the boss, so they overlap perfectly. Then, it shifts 50
	-- studs in the y-direction. It is now 50 studs above the boss.

	awesomeprojectile.CFrame = awesomeprojectile.CFrame * CFrame.Angles(math.rad(90),0,0)
	-- The projectile's position and rotation are maintained. Then,
	-- it rotates 90 degrees along the x-axis, similar to a top rotating
	-- around its center. It is now facing in the direction I want.

	local bv = Instance.new("BodyVelocity", awesomeprojectile)
	bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
	bv.Velocity = args[3]
	-- velocity shenans. Unrelated.
