Per the patch notes:
When we reworked sword skill 5 from Grasping Shadow to Deathstrike, we also carried over the slow and chill conditions it inflicted. However, since Deathstrike is a damage skill rather than a control skill like Grasping Shadow, we are removing this component because it muddies the new purpose of the skill. Similarly, we are reworking both Embrace the Darkness and Unyielding Anguish in the Mallyx stance that both act as pulsing areas of effects, with the intent of better differentiating when they should be used. Embrace the Darkness is being focused on inflicting torment. Unyielding Anguish is being revamped, becoming a setup skill that gathers up enemies, and it has been renamed Call to Anguish. Beyond these changes, we are also scaling up skills and traits that looked like they were just marginally out of play and reducing some might generation in PvP.
-Impossible Odds: Instead of pulsing superspeed, this skill now increases your movement speed by 50%. Reduced damage of the secondary strike by 19% in PvP only.
-Hardening Persistence: Increased the damage reduction per pip of energy from 1% to 1.5%.
-Focused Siphoning: Increased power scaling by 400% in PvE only. Increased healing scaling by 400% in PvE only.
-Spear of Anguish: This skill now scales torment duration dynamically based on distance rather than using distance thresholds.
-Notoriety: Reduced might duration from 10 seconds to 5 seconds, and reduced the number of stacks applied by 1 in PvP only.
-Icerazor's Ire: Increased damage by 30%.
-Elemental Blast: Reduced recharge in PvE from 12 seconds to 10 seconds. Fixed an incorrect radius tooltip.
-Shining Aspects: Removed the internal cooldown from this trait.
-Rapid Flow: Increased base healing by 50%.
-Shackling Wave: Reduced the damage of secondary strikes by 20% in PvP and WvW.
-Deathstrike: This skill no longer chills or slows.
-Burst of Strength: Reduced the damage of this skill in WvW to match the PvP version. Increased the bonus damage boon from 15% to 25% in PvE only.
-Unyielding Anguish: This skill has been reworked and renamed Call to Anguish. It is now a leap finisher skill that pulls foes to the center of your landing point and chills them. This skill has an energy cost of 35 and a 5-second recharge.
-Embrace the Darkness: This skill is now a mobile dark field. Increased recharge to 10 seconds. This skill no longer grants a stat increase and is no longer unblockable and unblindable. The amount of torment applied per pulse is unchanged, but using a skill that costs energy now increases the stacks of torment applied on the next pulse by 2. This skill now deals a small amount of damage each pulse.
