Guild Wars 2

quick questions i was wondring how fire dmg is calculated since it stacks for duration and not intensity? for ex: if i use my signet of fire for 3k dmg over 8sec then fire breath that does 1.5k over 8 sec as well how is the dmg calc?

It’s burn damage – condition.
Fire breath does as well, normal damage which goes along with burning.

all burning is calculated the same. Just some burning abilities are applied continusly in additional ticks, like drakes breath, fiery eruption. So the tooltip says 4x 3 seconds of burning, and gives the total damage for the whole 12x(0.25*Con+328).
