Update: Rift 1.6.1 Hotfix 8

GENERAL

 * Auction Houses now list and allow you to bid on items from both Guardians and Defiants.
 * Instant Adventure: Jaron Ply and his buddies are no longer super powerful on PvP Shards.
 * Fixed an issue that could cause some abilities gained while on an Instant Adventure to be removed when your character died.
 * Ember Isle: Added a graphical warning circle around Ochrin's spawned gold piles.
 * Rift: Endangered Souls: Made the Ravenmournes' ghostly form more resilient to damage.
 * Item: Dark Pulsing Crystal is no longer flagged Unique.
 * The duel radius (the distance you can move before exiting a duel area) has been tripled!
 * All critters in Meridian and Sanctum are now unable to be targeted by hostile player effects - and should no longer cause duels to be cancelled if they get caught in an AoE.

HAMMERKNELL

 * Runeburst Umbrals' Torment ability no longer pulls players into the center of the effect. The time between damage ticks has been increased and the total duration of the effect reduced.

 * Rune King Molinar: Increased the allowable gap between Molinar and Dollin's health to 7% from 4%.
 * Rune King Molinar: Forgotten Stewards have gained a newfound sense of fortitude, and can no longer be killed by Ascended. Luckily, they're still able to sacrifice themselves if so inclined!
 * Rune King Molinar: Runic Feedback is slightly more forgiving at the start of the effect.
 * Terror Bombardment is now interruptible.

RISE OF THE PHOENIX

 * General Silgen's bombs now have 4 seconds in which to be dispelled.
 * Beruhast will only summon 2 Flaming Vortices at 20% health, rather than 3.
