I have frapsed it. And yeap, it does stack. No ticks are lost.
Also few, known or not quite things:
- dot does damage every 3s (90-91 frames)
- when phrases are stacked, ticks occur more often (duh)
- ticks deal constant damage, with the exception of closing tick (which usually hits for less, and depends on how much dmg there is left to deal)
- first tick always does it's damage instantly, at the moment of dot appliance
- intellect does NOT affect per-tick damage
- hit quality (crit/hit/graze) does NOT affect per-tick damage
- hit quality (crit/hit/graze) influences only the linger phase (x1.5/x1/x0.5)
- at 10 might, every tick deals 10..10.4 slash and burn damage; which is then reduced by 1/4 of enemy's respective DR.
Okay so thats why DR seemed to have little effect. Am I right in concluding that 20 Slash DR only reduced the tick damage by 0.5 over 10 DR?
Now I wonder is there anything except Int, Might and Accuracy that can increase the damage (either through bigger ticks or longer duration)?
