Tempest Rush

Tempest Rush is a Secondary Monk skill.

It is one of the few skills that truly benefit from Hexing Pants of Mr. Yan.

In-game
While active, the Monk will forcibly move (using this skill does not break any existing Immobilize effects, but renders the Monk immune to them while channeling; cannot be cast if Immobilized), hitting enemies they collide with for 390% damage per tick, roughly 10 yards radius. Damage is done once every 12 frames (5 times each second).

Under the Tempest Rush, the Monk may move through enemies freely, but not through obstacles and walls. This skill is especially effective with Momentum.

Runes

 * Northern Breeze: damage type changes to Holy, reduces the channeling cost of to 25 Spirit, and increases damage to 500% (unlocked at level 11).
 * Tailwind: also increases the movement speed by 25% while the Tempest Rush is active. This increase ignores the normal 25% limit (unlocked at level 20).
 * Flurry: damage type changes to Cold. While channeling, the Monk builds up Flurry stacks, up to 100, at the rate of 3 stacks per tick. When the channeling stops, all enemies within 15 yards of the Monk suffer 90% damage as Cold for every stack of Flurry. The stacks are cleared after the blast (unlocked at level 33).
 * Electric Field: damage type changes to Lightning, and while channeling, enemies within 20 yards are shocked for 135% damage as Lightning per tick (unlocked at level 45).
 * Bluster: damage type changes to Fire, enemies hit are knocked back and deal 20% less damage for 4 seconds (unlocked at level 56).
