How much damage does after burn do?
I know that burning enemies take extra damage from after burn, but how much damage does after burn deal?
From looking at the Creation kit, the fire spells have 3 attributes that determine after burn damage.
Taper Duration: How long the damage lasts.
Taper Weight: Multiplier of initial damage.
Taper Curve: This one I'm not sure of, but it's 2.0 for all of the fire spells. From playing around with it, higher numbers cause the afterburn damage to fall off faster. Negative values cause it to increase over time.
Interestingly, all spells except Wall of Fire have the same taper weight, .3. Wall of Flame has a taper weight of .5.
There is some curve that we can use to describe the after damage of each spell. For most of them, it's going to be 30% of the damage done, decreasing over time by some unknown (but constant across all spells) amount.
The burn duration of each spell is listed below:
- Flames: .1 Seconds
- Firebolt: 1 Second
- Fireball: 2 Seconds
- Incinerate: 1 Second
- Fire Storm: 4 Seconds
- Fire Rune: 1 Second
- Flame Cloak: 2 Seconds
- Wall of Flame: 2 Second, .5 Weight
