I'm currrently planning out my Mechromancer's Little Big Trouble skill tree build.
I would like to know if the Mechromancer's Electrical Burn skill also work with shock/electrocute status damage effects from other skills? (i.e. Shock Storm, Shock and "AAAGGGGHHH!", One Two Boom and Make it Sparkle [Deathtrap charged with a shock/electrocute weapon]) Will those skills also cause Electrical Burn to give a chance that enemies will burst into flames and take Burn damage? Or does Electrical Burn only work with shock/electrocute damage from guns?
When your Electrocute Status Effects deal damage to enemies, there is a chance they will burst into flames and take Burn Damage. The amount of Burn Damage is based on the Electrocute damage dealt.
Killing an enemy with a Critical Hit causes an Electric Storm, dealing Electrocute Damage to nearby enemies. Electrical Storms are also caused by Deathtrap whenever he kills an enemy.
Shock and "AAAGGGGHHH!"
Reloading your gun causes an Electrical Explosion, damaging nearby enemies.
One Two Boom
Deathtrap Ability. Deathtrap shoots out an orb of energy at an enemy. If you shoot the orb it will explode, dealing massive Shock Damage to nearby enemies.
Make it Sparkle
Shooting Deathtrap with an elemental weapon charges him with that element, causing his melee attacks to deal additional damage of that element.
EDIT: There is now an answer that explains how this works generally. Can anyone with experience on using the mentioned skills, comment or answer on which specific skills 'Electrical Burn' will cause burn damage effects with?
