Warlock Spell: Corruption

Corruption

Here’s my visualization of the spell cast. Above is the timeline. It’s dotted in 1 second intervals with an extra dark dot at each 5 seconds to make it easier to read.

The spell is cast at time 0. The “X” is the Global Cooldown (GCD) (1.5 seconds). The dotted purple/grey lines are where damage actually occurs. Assuming the dot runs for full duration it will do 6 ticks.

Min Total Damage = ({Min Damage} + ({Shadow Damage} * {Effective Coefficient})) * {1+Contagion bonus+Shadow Mastery bonus}

Assuming I have 1k bonus shadow damage each tick should hit for ~446 for a total of ~2677.

Relevant Talents:

Improved Corruption 5/5 – Make Corruption instant cast. It’s tempting to take it down to only 1.5 second cast (1.5 second cast, 1.5 second GCD) but that’s only useful if you can stand still and cast. By making it instant you can make it so that you can cast it while at a full run.
Empowered Corruption 3/3 – Your Corruption spell gains an additional 36% of your bonus spell damage effect.
Contagion 5/5 – Increases the damage of Curse of Agony, Corruption and Seed of Corruption by 5% and reduces the chance your Affliction spells will be dispelled by an additional 30%
Nightfall 2/2 – Gives your Corruption or Drain Life spells a 4% chance to cause you to enter a Shadow Trance state after damaging the opponent. The Shadow Trance state reduces the casting time of your next Shadow Bolt 100%.
Shadow Embrace 5/5 – Your Corruption, Curse of Agony, Siphon Life and Seed of Corruption spells also cause the Shadow Embrace effect which reduces physical damage cause by 5%.
Shadow Mastery 5/5 – Increase the damage dealt or life drained by your Shadow Spells by 10%

The icky math

Affliction Shadow based DoT (cannot crit). 6 total ticks. Every 3 seconds.

Rank Mana min max duration Effective Coefficient (with downranking)
8 370 1032 1038 18 sec 93.6% (129.6% with Empowered Corruption)
7 340 942 948 18 sec
6 290 762 768 18 sec
5 225 558 564 18 sec
4 160 372 378 18 sec
3 100 252 258 18 sec
2 55 100 105 15 sec
1 35 44 48 12 sec

Min Total Damage = ({Min Damage} + ({Shadow Damage} * {Effective Coefficient})) * {1+Contagion bonus+Shadow Mastery bonus}
Min Total Damage = (1032 + (1000 * 1.296)) * 1.15
Min Total Damage = 2677.2

Min Damage/Tick = Min Total Damage/ number of ticks
Min Damage/Tick = 446.2
