Changes: Sextant of Unstable Currents

Revision as of 22:50, 7 January 2010

Sextant of Unstable Currents is an epic trinket for DPS casters.

Source

This item drops from Fathom-Lord Karathress in Serpentshrine Cavern.

Notes

There is an internal cooldown that prevents this trinket from proccing more than once every 45 seconds.
The proc chance is 20%.

Effective Damage

The effective +damage granted by this trinket is achieved in a method almost identical to that of [Shiffar's Nexus-Horn]. Essentially, to get the most out of this trinket, you want shorter cast times, and higher crit.

The formula for calculating the amount of effective +damage granted by Sextant of Unstable Currents is -

E = 190 * 15 / (45 + (t / (0.2 * c)))

Where...

E = effective +damage
t = cast time
c = critical strike chance

The following Java Program can be used to obtain a table of effective +damage for different casting speeds:

   public static void main(String[] args)
   {
       float crit;
       float time;
       float effective;
       for(time = 1; time < 6.5f; time += 0.5f)
       {
           for(crit = 10; crit < 101; crit++)
           {
               effective = 190 * 15 / (45 + (time / (0.2f * (crit / 100))));

System.out.println("" + crit + "" + time + "" + effective + "");

           }
       }
   }
