Summoners War: How to Identify and Roll Endgame God-Tier Artifacts

To identify an endgame god-tier artifact in Summoners War, look for at least three concentrated upgrade rolls (triple or quad rolls) into synergistic substats that directly match your monster's mechanical kit. True top-tier artifacts feature stacked, high-impact modifiers rather than scattered, general utility lines.

Before committing scarce mana and conversion materials, evaluate base substats, power up in disciplined stages, and sell pieces that fail key roll checks early.

Priority Modifiers by Monster Archetype

Endgame artifacts function as specialized kit amplifiers rather than generic stat sticks. Matching the modifier category to the monster's attack pattern or defensive role determines its actual effectiveness in World Arena and Guild Siege.

Multi-hit attackers gain little value from pure Critical Damage modifiers because their offensive output relies on stacking unmitigated true damage across several hits. Conversely, single-target nukers with high multipliers need Skill Critical Damage to guarantee kill thresholds through enemy shields and damage reduction passives.

Power-Up Milestones and Sell Filters

Evaluating an artifact requires testing its roll distribution at specific enhancement breakpoints. A Hero artifact that concentrates its rolls into optimal stats consistently outperforms a Legend artifact with scattered rolls across four unrelated lines.

Follow this upgrade sequence to conserve mana:

1. Inspect Starting Substats: Keep Hero or Legend artifacts that possess at least two synergistic base properties, such as Additional Damage lines, specific Skill Critical Damage, or elemental damage reduction. Sell base pieces with four scattered, low-impact utility lines immediately.
2. The +6 Breakpoint Check: Enhance the artifact to +6 first. If the first two upgrades roll into conflicting, low-priority lines (such as flat accuracy on a primary damage dealer or weak utility like Life Drain), stop immediately and sell the piece.
3. The +9 and +12 Decision: If both rolls at +6 land on target substats, continue powering up to +9 and +12. A keepable endgame piece must hit at least a triple roll into your target synergy profile.
4. Identify Junk Base Lines: Avoid heavily investing in base pieces featuring niche stats like Bomb Damage, Recovery Skill, or First Turn Single-Target Damage Reduction unless you are configuring a monster specifically designed around that single mechanic.

Using Conversion Stones to Finalize Rolls

Artifact conversion allows you to replace one unwanted line on a piece with an optimal modifier. However, converting an artifact locks all other lines, preventing any future changes to those remaining substats.

• Never convert a scattered artifact: Do not use Conversion Stones on artifacts that failed to roll three or four times into desirable substats. Conversion fixes a near-perfect piece; it cannot rescue a mediocre one.
• Target the single junk line: Use conversion exclusively on pieces with heavily stacked primary stats to eliminate an irrelevant secondary line, such as Life Drain or Flat Recovery, replacing it with Additional Damage or elemental damage reduction.
• Refine the converted line: After applying a Magic, Hero, or Legend Conversion Stone to set the desired stat, use lower-grade stones on that same slot to continuously reroll the percentage until you achieve an optimal roll value.
