Changes: Shiffar's Nexus-Horn

Revision as of 19:49, 16 March 2009

Shiffar's Nexus-Horn is a powerful caster trinket that has a chance to give a buff to spell damage after criting.

Source

Drops from Harbinger Skyriss in the Arcatraz, the 3rd wing of the Tempest Keep on both normal and heroic difficulty.

Notes

There is an internal cooldown that prevents this trinket from proccing more than once every 45 seconds.
It can proc off anything that is considered a spell and that can crit, this includes Healthstones and Heals.

Effective Damage

The effective +damage granted by this trinket is affected primarily by cast time and critical strike chance. This trinket gains more benefit from shorter cast times and higher critical strike chances.

The formula for calculating the amount of effective +damage granted by Shiffar's Nexus-Horn is -

E = 225 * 10 / (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 = 225 * 10 / (45 + (time / (0.2f * (crit / 100))));

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

           }
       }
   }

The four main(Base) casting speeds which should be considered, along with a shortened table for each, are given below:

1.5s - Scorch, Searing Pain, Wrath

Base Crit %	Cast Time	Effective +Damage
20.0	1.5	27.272728
25.0	1.5	30.0
30.0	1.5	32.142857
35.0	1.5	33.870968
40.0	1.5	35.294117
45.0	1.5	36.486485
50.0	1.5	37.5

2.0s - Lightning Bolt

Base Crit %	Cast Time	Effective +Damage
20.0	2.0	23.68421
25.0	2.0	26.470589
30.0	2.0	28.723406
35.0	2.0	30.582525
40.0	2.0	32.142857
45.0	2.0	33.471073
50.0	2.0	34.615383

2.5s - Frostbolt, Shadowbolt, Incinerate

Base Crit %	Cast Time	Effective +Damage
20.0	2.5	20.930233
25.0	2.5	23.68421
30.0	2.5	25.961538
35.0	2.5	27.876106
40.0	2.5	29.508196
45.0	2.5	30.91603
50.0	2.5	32.142857

3.0s - Fireball

Base Crit %	Cast Time	Effective +Damage
20.0	3.0	18.750002
25.0	3.0	21.428572
30.0	3.0	23.68421
35.0	3.0	25.609755
40.0	3.0	27.272728
45.0	3.0	28.723404
50.0	3.0	30.0

For comparisons sake, [Icon of the Silver Crescent], if used every cooldown, adds 68.7 +damage (25.7 +damage coming from its on-use effect).
