Fist of the Heavens (Diablo III)

Fist of the Heavens is a Secondary  skill, based on the Paladin skill of the same name.

In-game
When cast, strikes the targeted location anywhere within 60 yards. Can be cast over walls and terrain. The charged bolts are released evenly in 6 directions, and travel up to 40 yards, piercing through enemies. Each of the sparks deals full damage.

Runes

 * Divine Well: damage type changes to Holy, and each bolt also zaps all enemies within 20 yards of itself as it travels, dealing 40% damage as Holy per tick.
 * Heaven's Tempest: damage type changes to Fire, and the pillar also leaves behind a storm with 8 yard radius for 5 seconds, dealing 100% damage as Fire per second to enemies who pass underneath it.
 * Fissure: the pillar also leaves behind a fissure of lightning energy that deals 410% damage over 5 seconds within 8 yards. If there is another fissure nearby, lightning arcs between them every second, dealing 135% damage as Lightning to reached enemies. Each fissure connects to every other fissure within 40 yards.
 * Reverberation: the pillar also throws enemies away from the blast, up to 30 yards, and slows them by 80% for 4 seconds. This only affects the pillar: charged bolts do not have this effect.
 * Retribution: damage type changes to Holy, and the pillar is replaced with a massive piercing bolt thrown by the Crusader. It travels to the targeted location, dealing 270% damage as Holy to every enemy is passes through. At the targeted location, it explodes, dealing 435% damage as Holy within 8 yards and releasing 6 piercing charged bolts as usual, each dealing 185% damage as Holy to enemies they pierce through.

Non-rune enhancements

 * Darklight (Legendary Flail): increases damage by 800-1000%, and each casts also casts the second free Fist of Heavens at the same location. Retribution rune fires twice, with a short delay.
 * Khassett's Cord of Righteousness (Legendary Belt): reduces Wrath cost by 40% and increases damage by 130–170%.
 * Aegis of Valor (Set Bonus for 2 items): Attacking with Fist of the Heavens increases Heaven's Fury damage by 100% for 5 seconds, stacking up to 3 times multiplicatively.
 * Aegis of Valor (Set Bonus for 4 items): Hitting with Fist of the Heavens generates 5 Wrath and reduces damage taken by 1% for 5 seconds, stacking up to 50 times.
 * Aegis of Valor (Set Bonus for 6 items): increases damage by 20,000%.

Development
The ability was the first one to be completed for the Crusader, in terms of how the skill worked and its supporting art.
