Hidden Details on Olroth's Legacy in Item Filter Info for 0.5 | Path of Exile Return of the Ancients

Summary

  • Olroth’s Legacy is a new rune in patch 0.5 that allows players to destroy an Ezomyte or Kalguuran unique item to extract one of its modifiers as a socketable unique rune.
  • The extracted rune must be socketed into an item of the same class (e.g., a modifier from a two-handed mace must be placed into another two-handed mace).
  • Modifiers may have their values “toned down” compared to their original unique item to balance the fact that they can now be placed in high-tier crafted gear.
  • The system creates new possibilities for build customization, potentially allowing players to combine powerful unique modifiers with superior base items.

How Olroth’s Legacy Works

The core mechanic involves using the Olroth’s Legacy rune on specific unique items. This process destroys the original unique to create a unique rune. A significant question remains regarding whether the modifier extracted is chosen at random from the item’s pool or if it is a predetermined, specific modifier.

Notable Unique Items and Potential Modifiers

The following items were highlighted from the item filter information as having impactful modifiers for potential extraction:

  • Blackbraid (Body Armour): The modifier applying armour to elemental damage could be highly valuable if moved to a better-crafted body armour.
  • Iron Grasp (Body Armour): Contains the “Iron Grip” and “Iron Will” keystones, which are vital for strength-stacking builds.
  • Chernobog’s Pillar (Shield): Offers “gain 1% of damage as fire damage per 1% chance to block,” which could remain strong even if efficacy is reduced.
  • Alkem Eira (Shield): Provides “damage blocked is recouped as mana,” offering defensive utility when paired with block-recoup technology.
  • Trenchtimbre (One-Handed Mace): Features “increases and reductions to minion attack speed also affect you,” which can be used to bypass lower base attack speed on attack-focused builds.
  • Mjolner (One-Handed Mace): Could potentially offer “level of lightning skills” or other powerful lightning-themed mods.
  • Hoghunt (Two-Handed Mace): Provides a local critical hit chance modifier that would be extremely powerful if applied to other high-base-crit weapons.
  • Hrimnor’s Hymn (Two-Handed Mace): Offers an additional aftershock for slam skills.
  • Brain Rattler (Two-Handed Mace): Grants “all damage with this weapon causes electrocution build up,” providing a powerful stun-like elemental ailment.
  • Quill Rain (Bow): Includes local increased attack speed and arrow speed, which are highly desirable for bow builds despite potential damage penalties.
  • Amor Mandragora (Talisman): Likely provides the “Druidic Prowess” buff, granting increased skill speed.
  • Svalinn (Shield): Known for its “lucky block” mechanic; it is unclear if this specific benefit can be extracted.
  • Keeper of the Arc (Helmet): Alternates damage reduction from hits and damage over time every 5 seconds.
  • Olrovasara (One-Handed Mace): Grants added lightning damage based on enemy power, ideal for boss encounters.
  • Crown of Thorns (Helmet): Provides the “Pain Attunement” keystone, potentially allowing builds to access it without pathing to it on the tree.
  • Deathblow (Gloves): Offers built-in “Culling Strike.”
  • Legionstride (Boots): Provides base block chance, useful for scaling defense without a shield.
  • Trampletoe (Boots): Deals a percentage of overkill damage to nearby enemies, aiding clear speed.
  • Wanderlust (Boots): Grants immunity to slows; even at reduced efficacy, this is expected to be a strong defensive rune.
  • Starkonja’s Head (Helmet): Features damage redirection to companions, useful for Spirit Walker builds.
  • Elevore (Helmet): Provides passive charm charge generation.
  • Twisted Empyrean (Mace): Offers high flat cold damage and fire-to-cold conversion for mace skills.
  • Ironbound (Bow): Features “arrows return if they have pierced a target which had fully broken armor,” effectively allowing for double damage.
