First off, all thanks go to Valkemen and his friend Astehnir for testing out this info.
Over on the monk boards the community was compiling info on the undocumented patch changes and we came across something weird. The DoT component of Exploding Palm was showing different figures then the talent calculator as well as different figures for different people. Upon some testing done by Valkemen and Astehnir they found that the DoT was scaling with weapon speed, the faster the weapon the more damage the DoT did.
Testing has found that the formula is relatively simple:
Weapon Dmg % x Weapon APS* = Actual Damage.
*Dual wielding gives the main hand weapon a bonus of 15% APS.
The Exploding Palm DoT does a base 65% weapon dmg per second, if a monk is using a 1.2 APS weapon the DoT will now deal 78% (65 x 1.2=78) wpn dmg per second. A dual wielding monk with a 1.2 APS main hand weapon will deal 89.7% (65 x (1.2 x 1.15)=89.7) wpn dmg per second.
After this was discovered for the Monks we decided to test out the only other class with a DoT within the beta, the WD and some strange things were discovered.
As excepted Firebats scales it's damage in the same exact way, it was 100% wpn dmg x APS = actual dmg per second. Surprisingly, the DoT component of Poison Dart did not scale at all with APS. Not being satisified with such a small sampling of abilities Valkeman and Astehnir decided to load up an emulator and check other abilities that may have scaled in a similar fashion.
They found the following abilities all scale their damage on APS in the same exact way:
Grasp of the dead
With this it would seem that certain pets also scale their damage on the APS of the caster. There are many other abilities/pets/summons from other classes that need to be tested out either in an emulator or the beta (Call of the Ancients, Companion, Sentry, etc) and many, many rune effects that will need to be tested once the game goes live.
Also not being in the beta I can't test it but would like to know if anyone has any experience with DoTs critting.
DoT and Pet Damage Formula:
Single Weapon (1h or 2h)
Base Weapon Damage % x Weapon APS = Final Damage Total
Base Weapon Damage % x (Main Hand Weapon APS x 1.15) = Final Damage Total
