Notes

• Spells cast due to this talent behave completely equal to their base spells.
• The net effect of this talent (maxed) is a 16.5% average damage increase for the lightning spells. (.5 damage * .33 chance = .165)
• LO procs seem to be able to proc LO as well , while the damage the resulting spell does is still calculated as half of the original one.

Patch changes

•  Hotfix (2009-05-14): "The chance for the Lightning Overload talent to be triggered is being increased from 7/13/20% to 11/22/33%."
  
• Patch 2.3.0 (13-Nov-2007): (Elemental) now has a 4/8/12/16/20% chance to occur and the additional spell causes half damage and no additional threat.
              Prior to that the chance was {1/2/3/4/5}%, but spell's damage was not halved.
