Screech Agro

May 30, 2008 at 10:30 am (Game Design, Hunter, Pets, Warcraft, World of Warcraft) (, , )

Keeping things short and sweet for those with ADHD:

  • Screech generates about 128 threat in addition to threat from damage
  • The 128 threat is not divided between mobs affected by the debuff, each gets the full effect.
  • That’s crazy.
  • If you’re trying to maintain agro, you should turn off claw and/or bite and only use screech.
  • If you’re trying to maximize damage, you should turn off screech and use claw instead.
  • There seems to be some scaling of screeches damage…

And now for what’s sure to be a wall of text and math.

Methodology

No threat meters were used. I turned off all auto-casts, and turned on stay and passive. I then used Eyes of the Beast to agro ogres in the blasted lands. I then applied 5 screeches, and recorded the damage done. After ending the EotB effect, I stayed at ranged and waited for sufficient damage before applying different ranks of mend pet without over healing. To determine the debuff’s threat

(HP healed) / 2 > [(total damage done in 5 uses) + (debuff threat x 5)] x 1.3 > (HP healed – 1 tick) / 2

or

(((HP healed / 2) / 1.3) – damage done) / 5 = debuff threat

I did a few single tests to get an initial value for the debuff and then attempted several tests with 2 mobs agroed at the same time before applying screech. I ran into a problem that once the first mob, agroed and I killed it, the pet would return to my side with the other in tow. I then had to get back to ranged before continuing to heal. This exchange seems to have caused an error where I was not far enough away to receive the 30% cushion and instead agroed at 1.1. I also had some huge lag spikes which seems to have thrown off my other test.

Tests

#1- single target

Damage done: 317 (I didn’t record individual numbers for this one)

Healing: 20 x 125 (MPr1)

Calculations:
Max value: (((2500 / 2) / 1.3) – 317) / 5 = 128.91 debuff threat
Min value: (((2475 / 2) / 1.3) – 317) / 5 = 126.98

#2- single target

Damage done: 69 + 49 + 61 + 43 + 51 = 273

Healing: (1 x 1400 (MPr6)) + (7 x 125 (MPr1)) + (4x 25 (4 tics of Mpr1)) = 1400 + 875 + 100 = 2375

Calculations:
Max value: (((2375 / 2) / 1.3) – 273) / 5 = 128.09 debuff threat
Min value: (((2350 / 2) / 1.3) – 273) / 5 = 126.17

#3- 2 targets

Target 1

Damage done: 0 (not targeted by screech, but within melee range)

Healing: (1 x 700 (MPr4)) + (7 x 125 (MPr1)) + (4x 25 (4 tics of Mpr1)) = 700 + 875 + 100 = 1675

Calculations:
Max value: (((1675 / 2) / 1.3) – 0) / 5 = 128.85 debuff threat
Min value: (((1650 / 2) / 1.3) – 0) / 5 = 126.92

Target 2

Damage done: 43 + 58 + 48 + 132 + 47 = 328

Healing: (1 x 700 (MPr4)) + (9 x 125 (MPr1)) + (1 x 250 (MPr2)) + (2x 50 (2 tics of Mpr2)) = 700 + 1125 + 250 + 100 =2175

Calculations:

Max value: (((2175 / 2) / 1.3) – 328) / 5 = 101.71 debuff threat
Min value: (((2125 / 2) / 1.3) – 328) / 5 = 97.86

Recalculate assuming melee agro:

Max value: (((2175 / 2) / 1.1) – 328) / 5 = 132.13 debuff threat
Min value: (((2125 / 2) / 1.1) – 328) / 5 = 127.58

(whew- By the way, the reason i had to use rank2 is my pet was really close to dying.)

#4- 2 targets

Target 1

Damage done: 0 (not targeted by screech, but within melee range)

Healing: (2 x 700 (MPr4)) + (2 x 125 (MPr1)) + (1x 25 (1 tics of Mpr1)) = 1400 + 250 + 25 = 1675

Calculations:
Max value: (((1675 / 2) / 1.3) – 0) / 5 = 128.85 debuff threat
Min value: (((1650 / 2) / 1.3) – 0) / 5 = 126.92

Target 2

Damage done: 53 + 40 + 48 + 62 + 49 = 252

Healing: (2 x 700 (MPr4)) + (7 x 125 (MPr1)) + ((3x 25 (3 tics of Mpr1)) = 1400 + 875 + 75 = 2350

Calculations:

Max value: (((2350 / 2) / 1.3) – 252) / 5 = 130.37 debuff threat
Min value: (((2325 / 2) / 1.3) – 252) / 5 = 128.45

Recalculate assuming lag caused agro to appear a tick late:

Max value: (((2325 / 2) / 1.3) – 252) / 5 = 128.45 debuff threat
Min value: (((2300/ 2) / 1.1) – 328) / 5 = 126.52

Data Summary

Max values: {128.91, 128.09, 128.85, 132.13, 128.85, 128.45)

Min values: {126.98, 126.17, 126.92, 127.58, 126.92, 126.52)

-> Value of Screech’s debuff is between 127.58 and 128.09.

Conclusions:

  • For most purposes a value of 128 threat can be assumed for any targets affect by the screech debuff.
  • Screech’s physical damage does not have a hidden threat component.
  • Screech’s threat from debuff is not divided between targets (unlike warrior’s demoralizing shout).
  • Screech’s physical damage seems to be above expected values and may scale.

Further testing

Screech is supposed to have a damage range from 33-61 for average damage of (47 x 1.15 = 54.05), yet it the lowest value recorded is 40, there are several values above 61 {69, 132 (66 crit), 62), and average damage is 62.3. It appears to be dealing an additional 8 damage per use. Is there scaling going on?

I did not change gear or buffs throughout testing. It is possible that damage or debuff threat scales with RAP in some way.

I used the same rank of screech for each test. It is likely that the threat generated depends on the rank of screech.

It is possible that threat is affected by the level of the pet. A level 70 was used in this test.

    Very impressive work. Helps explain so clearly why I love my owls (and my new raven =)

    With no cooldown on screech, this might be a factor for those who have plenty of crit as well.

    I used to use a flying pet for the reason of screech. I got tired of mend pet pulling aggro. However, with a patch several months ago, I noticed the sound effect from screech changed and for some reason was 10 times more annoying. To the point I gave up the bird for a cat.

    I had read somewhere you can put an empty .wav file named “Screech.wav” somewhere in the WoW folders that would make WoW use the blank wav instead of the default Screech sound, thus nullifying any sound from Screech. I haven’t tested this yet, but once I’m not so lazy, I will. Feel free to try this out if you can and let us know if you got it working! I’d love to use screech again.
