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 + "");
} } }
