Imperial Guardian — Elemental Instance Event

Imperial Guardian (IG) is a repeatable elemental instance dungeon where players defend against waves of elementally-attuned monsters. It is the primary source of Spider Artifact Fragments — the building blocks for the Spider Artifact system, one of Season 21's most powerful passive stat systems.

Weekly Element Rotation

Imperial Guardian monsters spawn with a weekly elemental attribute. This affects which Pentagram element you should equip for maximum advantage:

Week Pattern Element
Week 1 Fire
Week 2 Water
Week 3 Earth
Week 4 Wind
Week 5 Darkness
Week 6 Random
(Repeats) Cycles through

Tip: Equip a Pentagram with the element that is strong against the current week's element. Elemental advantage gives significant damage and defense bonuses.

Spider Artifact Fragment (Cat=20,95) ~60% Craft Spider Artifacts
Artifact Enchantment Stone ~40% / ~20% Enchant Spider Artifacts
Elite Artifact Enchantment Stone Rarer High-level enchanting

Spider Artifacts

Spider Artifacts are equippable passive items (7 types) that provide permanent combat bonuses. They are crafted from Spider Artifact Fragments obtained in Imperial Guardian.

Each of the 7 artifact types offers different stat boosts:

  • Type 1–6: Various stats (damage, defense, speed, HP, etc.)
  • Type 7: Ultra-rare (0.042% craft chance) — significant all-round boost

Craft Spider Artifacts at the Spider Artifact NPC using your accumulated fragments.


Strategy

  1. Farm IG consistently — Spider Artifacts require many fragments; daily IG runs compound quickly.
  2. Use the correct element — Equip a Pentagram countering the week's element for maximum efficiency.
  3. Higher tiers = more fragments — Always enter the highest IG level your character can access.
  4. God of Darkness farms Enchantment Stones — For artifact enchanting materials, see the God of Darkness guide.
