Epiphany

Epiphany is a Focus Monk skill, introduced with the release of Reaper of Souls.

In-game
Epiphany turns the Monk into a holy apparition, similar to those summoned by other skills like Seven-Sided Strike. While it lasts, the Monk increases Spirit recovery and automatically teleports to the enemy when performing any melee attack, or travels a minimum required distance to approach the target. The mechanics are same as those of the Fists of Thunder, except for maximum teleportation range is unlimited (anywhere within the screen borders).

In addition, while Epiphany is active, the Monk is immune to Crowd Control effects. Existing effects, even those that normally disable character control, are cleared.

Runes

 * Desert Shroud: also reduces all unsaved damage taken by 50% for the duration.
 * Ascendance: when casting Epiphany, and every time the Monk travels 10 yards (including teleportation), gain a charge of Ascendance (can only store one). Any damaging attack will consume that charge and Stun all affected enemies for 1.5 seconds.
 * Soothing Mist: also causes all activated abilities to heal both the Monk and and allies within 30 yards. The amount of Life replenished scales with level, up to 16093 at level 70, and additionally increases by 4% of the Monk's Health Globe Healing Bonus.
 * Insight: increases the Spirit generation of Epiphany by additional 25 per second, to a total of 45.
 * Inner Fire: each attack releases a piercing fireball that travels up to 60 yards, burning enemies it passes through for 353% damage as Fire. Attacks that do not have a specific target (such as Tempest Rush or Seven-Sided Strike) instead cause each affected target to be hit for 353% damage as Fire, but no more than once per tick. If no targets are hit, hits a random enemy within 40 yards. Visually, causes fiery silhouettes to momentary appear by the enemies.

Non-rune enhancements

 * Rabid Strike (Legendary Fist Weapon): all Spirit spender skills that teleport the Monk while Epiphany is active are also mimicked on a nearby target for free.
 * Halcyon's Ascent (Legendary Amulet): Upon casting Epiphany, makes nearby enemies jump uncontrollably for 6-8 seconds.
