Update: Rift 1.8 Hotfix 4

Namplates!

 * We’ve been working behind the scenes on a highly requested UI feature – Nameplates allow you to easily see the status of those around you while keeping your eyes on the fight!
 * By default, nameplates will replace the old health bars and appear above yours and your target’s heads while in combat.
 * We have a wide variety of settings, so customize to your heart’s content by going to Settings -> Interface -> Nameplates. You can swap between your customized settings and the default with Shift+V.
 * The options also allow you to turn the system off entirely, if desired.
 * Name colors can be customized in the Name Colors tab.

World Event

 * Increased the drop rate for Power Cells while on the quest Parcels through the Cracks.

Crafting/Items

 * The fishing artifact 'Trophy Stillmoor Devil' is now fishable in Stillmoor!
 * The description of all fish has been updated with the water depth and locations where they can be found.
 * Abandoning the 300 Skill Crafting Daily Quest will no longer remove the crafted items from your bags. However, you cannot have more than 4 of these items at any one time.
 * Mathosian Longbow daily quest recipe now correctly requires a Workbench instead of the Forge.
 * All Planar Attunement Tier 2 item enchants now require a lvl 50 item. Several runes now require items to be level 50 when applied.

Infernal Dawn

 * Maklamos the Scryer:
 * Removed the cast time from an interruptible ability used by the three Juggernaut golems – if interrupted, it would cause them to become active with a higher health value than intended.
 * Failing to “solve” the Crystal Essences now triggers the intended consequences instead of no consequences.
 * Reduced agro range and moved his encounter wall up the hallway a bit.
 * Rusila Dreadblade:
 * Iron Wrath can no longer be avoided by moving further than 30m away.
 * Increased Rusila’s movement speed, she no longer moves in slow motion compared to other Infernal Dawn bosses.
 * Fixed an issue that could cause Rusila to use certain abilities much less frequently than intended.
 * Dreaded Snipers will now respawn appropriately.
 * Warforged Firestorms are once again susceptible to mesmerize effects.
 * Adjusted the Baleful Inferno ability “Rupture” to allow it to be interrupted by more abilities.
 * Adjusted the Pyrefly ability “Ember Strike” damage.

Raids

 * Increased the amount of additional damage output granted by the Enrage buff.

Mage

 * Chloromancer
 * Due to its change to instant cast, Withering Vine now gives 9 Charge when cast. Down from 15.
 * Dominator:
 * Fixed an issue where Thunder Blast was not triggering Quick Thinking.
 * Fixed an issue where some control breaking abilities were removing both the root and damage effects of Storm Shackle. These abilities will now only remove the root effect.
 * Necromancer
 * Fixed an issue where Vengeful Spirit was not preventing the Shadow Revenant’s Blood Corruption from removing stacks of Deathly Calling.

Rogue

 * Riftstalker:
 * Rift Barrier no longer redirects damage dealt by abilities that cannot be reflected.
