Effective Haste Edit

The effective haste granted by this item is affected primarily by cast time. This trinket benefits more from shorter cast times. The formula for calculating the amount of effective haste granted by this trinket is:

E = 522 * 10 / (45 + (t / 0.1))

Where:

E = effective +haste
t = cast time

The following Java Program can be used to obtain a table of effective +haste for different cast times.

  public static void main(String[] args)
  {
      float time;
      float effective;

      for(time = 1; time < 6.5f; time += 0.5f)
      {
              effective = 522 * 10 / (45 + (time / 0.1f));
              System.out.println("<tr><th>" + time + "</th><td align=\"center\">" + effective + "</td></tr>");
      }
  }

This gives the results below:

Cast Time	Effective +Haste
1.0	94.90909
1.5	87.0
2.0	80.30769
2.5	74.57143
3.0	69.6
3.5	65.25
4.0	61.411766
4.5	58.0
5.0	54.94737
5.5	52.2
6.0	49.714287
