Damage over time scaling

Just a couple questions how damage over time scaling works, cause I’ve read a couple things but am still not 100% sure it’s correct.

  1. I read that the skill applying the DoT will apply it’s scaling TO the DoT. Say, I use Warpath to inflict Time Rot, my understanding is that Time Rot would be affected by both Strength scaling and damage scaling for Warpath on it’s skill tree. Even though Time Rot itself doesn’t have inherent Strength scaling either way.

  2. Another thing I’m unsure about is, whether flat damage increases would apply to the DoT. So if I apply a DoT via melee attack and have +5 to melee attack, would that add to the DoT as well? (Same with applying it via a Spell). My understanding is that DoTs are generally neither Attacks NOR Spells so no mod that applies to those would ever apply to the DoT.

Oh and also, if I increase the Duration of the DoT, does that reduce the tick rate or does it calculate the regular tickrate first and then lets it tick longer (increasing overall damage per application)?

DoTs do a set ammount of dmg. That dmg is scaled by your dmg over time increases and the other tags that scale with it. Bleed for example is a physical DoT so increases to Physical damage will increase Bleed dmg. Same goes for fire and ignite, lightning and shock and so on.
You see the tags for it in the skill description but you need to look out for skills that have a hit and a dot application because DoTs scale differently in those.

Flat damage is added to hit dmg and not DoT dmg. DoT dmg is increased by the according dmg types.

Longer DoTs = more ticks.

Ah, I found it in the game guide in the meantime. Didn’t think to check in “ailments” section at first. Yeah apparently ailments scale with whatever the skill that applies it scales with, which is kinda cool (and unexpected)

Plus the Damage over Time stat that irrelevant mentioned. Currently stacking DoT and Elemental DoT being on the Warlock for those reasons.
