Shenlong's Spirit

Shenlong's Spirit is a Monk-only minor class set in Diablo III.

This set is named after legendary Master Shenlong. It requires a character level of 60.

Pieces
The set consists of just two items, both of which are required to complete the set. Both pieces are Monk-only.
 * Shenlong's Fist of Legend (Fist Weapon)
 * Shenlong's Relentless Assault (Fist Weapon)

Set Bonuses (2 pieces):
 * The damage of Spirit Generators is increased by 2% for each point of Spirit the Monk has. When reaching maximum Spirit, all damage is increased by 350%, but the Monk no longer passively regenerates Spirit and 65 Spirit is drained every second, lasts until the Monk runs out of Spirit.

The second part of set bonus is not passive: it triggers when maximum Spirit is actually reached, and lasts until the Monk loses all Spirit. The zero Spirit regeneration is also not passive, and only active during the damage amplification phase: it sets spirit regeneration to -65 per second, regardless of previous value.

With proper build, this allows Primary skills to deliver tremendous amounts of damage, especially when coupled with Raiment of a Thousand Storms set and passive effects like Depth Diggers.

The 350% damage modifier at maximum Spirit is multiplicative to other similar bonuses.

Spirit Generators only include Primary skills, not other skills that replenish any Spirit: Fists of Thunder, Deadly Reach, Crippling Wave and Way of the Hundred Fists.

Since the Spirit drain is static (65 per second, not per tick), this bonus is especially effective with Attack Speed boosts like Flying Dragon. This set also works well with Raiment of a Thousand Storms and/or Inna's Mantra.

Development
Old (Pre-2.3) set bonus: The chance was roughly 25%, unaffected by the Proc Coefficient, and had a [3 / Attacks per Second] seconds internal cooldown. The ball traveled 60 yards in a straight line, dealing 1200% damage as Fire to enemies it pierced though.
 * +250 Dexterity
 * +4 Spirit regeneration per second
 * Chance on attack to release a piercing ball of energy.

Trivia

 * Shenlong, or Shen-Lung, is a Chinese dragon of storms, and one of the titles of Jackie Chan.
 * The set is possibly a reference to Ryu of the Street Fighter series series of fighting games. The weapons resemble Ryu's gloves. The English localization of Street Fighter II mistranslated one of Ryu's win quotes into referring to a mysterious "Sheng Long" instead of Ryu's signature uppercut. Another of Ryu's signature moves is sometimes called a fireball.
