Electrical Burn Damage (EBD) is a type of Damage over Time. It is reduced by Lightning Resistance. The default duration for Electrical Burn Damage is 4.0 seconds.
Electrical Burn Damage receives no bonus from +XX% Lightning Damage modifiers. It benefits from the Intelligence attribute, however. The formula to this is:
elementalDamageDV * ((intelligenceDV / 500) + 1)
This means, for every 50 points in Intelligence, Electrical Burn Damage is increased by +10%. 500 points in intelligence would add +100%.
The Dream Mastery has various skills that deal and increase Electrical Burn Damage. Storm Mastery also has some skills as of Anniversary Edition.
