Update: Rift 1.5 Hotfix 12

RIFTSTALKER

 * Guardian Phase: Now gives the Riftstalker a chance to Deflect attacks, reducing their damage taken by the Riftstalker's Deflect rating. Deflect rating is increased by Dexterity.

GENERAL

 * Players with old Sourcestone vouchers in their inventory can once again use them to create Sourcestone tokens.
 * Iron Pine Peaks: If you completed the quest 'The Missing Link' in Dayblind Hollows without immediately accepting the followup, 'Collecting Threads', you can now resume that quest chain.
 * All pre-existing Harbinger of Regulos items that haven't yet been added to your Companion list are no longer Soulbound (much like newly acquired Harbingers of Regulos).
 * Achievements: King's Breach [Expert]: Dogs of War should properly trigger once again. Hunter Suleng's Ethereal Warhounds are back to spawning at the correct level.

RIFTS AND INVASIONS

 * Hammer and Flame (level 45+) is now considered a Major zone event and has increased Inscribed Sourcestone and Crystallized Insight payouts.
 * Corrected an issue with certain Earth and Fire Rift creatures that weren't awarding experience though they were at least green to your character.
 * Resolved some lingering issues with Wardstones not appearing in some spots.
