Hard Mode in Sephiria (Root Decay) requires specific artifacts to survive. This guide covers the best defensive, offensive, and utility artifacts for Hard Mode stages, organized by tier.
S-Tier Hard Mode Artifacts
| Artifact | Category | Why It's S-Tier |
|---|---|---|
| Magma Orb | Elemental | Core of Plasma Judgment Staff build — essential for Stage 60 |
| Thundercloud Compass | Elemental | Lightning chain trigger — makes the Plasma loop work |
| Explosion Proof Vest | Defensive | Reduces trap damage — counters Machine Rebellion modifier |
| Neutralizer Noir | Combo | Essential for poison builds — increases stack count |
A-Tier Hard Mode Artifacts
| Artifact | Use Case |
|---|---|
| Oink Shaman's Necklace | Elemental amplification — extends status durations |
| Lightning Stone | Lightning damage — good for Superconductor builds |
| Sword Training Manual | Combat stat boost — general purpose |
| Charm of Strength | Attack boost — works with any weapon |
| Pouch of Black Tea | Poison application — core of poison build |
| Golden Crown of Arrogance | Risk/reward damage boost |
Modifier-Specific Artifact Picks
Violent Claw (enemy damage up)
Stack Explosion Proof Vest + Slim Cushion + Robe of Yearning for maximum damage reduction.
Blood Feast (enemies heal on hit)
Use Magma Orb + Thundercloud Compass — the Plasma build deals so much damage that enemy healing can't keep up.
Tension (no potions in boss fights)
Equip Sapote Fruit (passive HP sustain) + White Crust Bread (passive regen). Pair with Endurance talent 20 for the revive.
Vertigo (fewer artifact choices)
Use Wisdom talent 10 (forced Unique artifacts) to mitigate reduced selection. Chalcedony Key provides extra reroll economy.
