Following this thread from @Okkes about the damage of Soul Annihilation
There are some DoT from abilities with the same graduate damage calculation :
Taste of the Hunt
Wounding Shot
Arterial Strike
Gouging Strike
Toxic Strike
Strike & Ring the Bell
Their damages are dynamically affected by :
PL
Might
Weapon quality enchantment
Sneak attack, Deathblow, Streetfighter passive, Backstab (unmodded)
Soul Whip (and upgrades)
Fighter weapon spe
Great Sword modal
Two-Handed passive
universal damage bonuses (human spirit, Inspired Beacon, etc) like every DoT
That mean, with Taste of the Hunt from a Druid-Rogue with WotEP, every enemies take a Damage over Time that scale when the striker active the modal and being invisible, for example. Afflicting them with 2 afflictions unlock Deathblow for the current effect also.
With some numbers, for Arterial Strike (on a friendly target to see the damage directly) :
5.5 damages (when I striked) >> 6.7 (I active the Great Sword modal) >> 9.7 (stealth, Backstab)
Switching to another weapon seems to remove the Quality enchantment bonus to the DoT, but this last go back when re-switching to the initial weapon.
Toxic Strike's first DoT seems affected, but also by PEN.
The Stag's Carnage (with CP and unmodded) also profit from these bonuses.
Taste of the Hunt weapon attack profit from Spirit of Decay +1pen. In other hand, Soul Annihilation doesnt profit from Penetrating Vision (+1pen with cipher's spells) but only from Hammering Thoughts (+1pen with weapon).
