How many seconds does afterburn damage last?

Question

When an enemy is hit with a fire enchanted weapon they catch on fire and take additional damage over time.

How long does that last?

Answer 1

According to the creation kit, the taper duration (how long the spell lasts after it's cast) for each of the fire spells is:

• Flames: .1 Seconds

• Firebolt: 1 Second

• Fireball: 2 Seconds

• Incinerate: 1 Second

• Fire Storm: 4 Seconds

Testing on a few giants, this seems about right. Flames dies out almost immediately. Firebolt and Incinerate last the same length, Fireball and Fire Storm last longer.

The non-direct spells list taper durations of:

• Fire Rune: 1 second spell duration, 1 second taper

• Flame Cloak: 60 Second duration (time on self), 2 second taper

• Wall of Flame: 1 second spell duration, 2 second taper

Answer 2

The afterburn damage effect lasts for 7-9 seconds, but it depends on the spell/how much damage the enchantment does.
