Particle Descriptions

Parameters:
  Count: This is literal. The count parameter specifies how many particles to spawn at once
         with these exact same parameters.
  Spread: The starting position of each particle is a normal number with mean of the Location
          and standard deviation of the Spread, e.g. (Norm(Loc.X, Spread.X), Norm(Loc.Y,
          Spread.Y), Norm(Loc.Z, Spread.Z)). This means that 68% of the particles will be
          within the bounding box of +/- 1*Spread, 95% will be within +/- 2*Spread, and 99.7%
          will be within +/- 3*Spread for each coordinate.
  Speed: The effect of this is determined by each particle.

              I.e. a large speed will result in near-horizontal motion for a short time,
              followed by an upward drift.
  Vanilla usage: U/N

  NMS name: crit
  Appearance: A brown X mark parallel to the screen.

              The speed is taken as the std. dev of a gaussian blocks/tick speed.
              With a speed of 0.0F, they float down slightly.
              With a speed of 0.1F, they appear to "hop" midair.
              With a speed of more than 0.5F, they quickly scatter.
              They will appear out a maximum of spread * 2 blocks away.
