spell found in many video and computer games around 1990s and the first decade of the 21st century, wherein a lightning bolt strikes one target, then a second with decreased damage, a third, and so on, until its power has diminished beyond a tickle. Example games would be Heroes of Might and Magic 3, World of Warcraft, et al.
1. Solmyr's special ability is that he starts with the ability to cast chain lightning, one of the most powerful spells in Heroes of Might and Magic 3.

2. Elemental Shamans' Chain Lightning and Chain Heal spells are part of the reason why many World of Warcraft players choose them as their characters.

When, in the course of a game of dota or another hero based, warcraft 3 map, you have a hero possessing an ability called chain lightning. Upon using this ability, on usually shouts "Berp Chain Lightning!!!" as loud as they can, so as to alert the rest of the house as to what just happened. Often most exuberantly used after the player using the ability has just KS'ed his team mate or friend.

Some say that the ability 'Arc Lightning,' found on the popular dota character named 'Zeus,' also constitutes the use of Berp Chain Lightning, as its animation and effect are similar. Although this is still widely debated among linguistics and dota players alike, both sides agree that it still is pretty cool.

The original Chain Lightning spell dates back to 1st Edition AD&D's Unearthed Arcana by Gary Gygax, and dates back to 1985. It is a sixth level spell, and causes 1d6/level damage per level of the caster to its primary target (or half on a successful save vs. magic). It will branch out to nearby targets in a chain pattern, each subsequent strike doing one less 1d6 per branch, with as many branches as the caster has levels and will continue arcing until it is exhausted. It can be a tricky spell to use because it can hit allies or even the caster himself or herself.
The wizard casts a chain lightning spell, but since there are only a few enemies, one bolt in the chain strikes him instead.
