Wartune Ultra Artifact Stat Refining and Upgrade Guide

To optimize artifacts in Wartune Ultra, prioritize class-matched damage stats over raw Battle Rating (BR), avoid locking attributes until you roll two primary stats, and level equipped pieces evenly to trigger set resonance thresholds.

Stat Priorities by Slot

Artifacts provide large stat pools, but inflating BR with non-functional stats reduces actual combat performance. Substats must align with your class damage type and role to scale properly in PvE and PvP.

Class Attack (PATK or MATK): Must match your character class. Rolling PATK on a magic user increases nominal BR but contributes zero damage to combat abilities.
Penetration and Critical: Penetration bypasses enemy defensive values on bosses and PvP opponents. Critical rating improves the frequency of bonus multiplier procs on core ability rotations.
Health Points (HP): Universal survivability that protects against all damage sources, including true damage, making it more reliable than flat physical or magical defense.
Block and Defense: Secondary defensive stats suited for frontline durability, but lower in priority than damage penetration on offensive pieces.

Slot Type	Primary Desired Rolls	Secondary Acceptable Rolls	Rolls to Reroll
Offensive	Class Attack (PATK/MATK), Penetration	Critical, Damage Amplification	Off-class Attack, Flat Resistances
Defensive	Max HP, Class Defense	Block, Damage Reduction	Off-class stats, Low-tier Crit
Hybrid / Utility	Penetration, Max HP	Crit Resilience, Armor Piercing	Unfocused hybrid offensive rolls

How to Refine and Lock Substats

Refining materials deplete rapidly if locks are applied too early, because each locked line increases the currency cost of subsequent rerolls. Follow this sequence when refining an individual artifact:

Roll freely without locks: Reroll the base artifact until two top-tier primary stats (such as matching Attack and Penetration) appear in the same batch.
Lock core stats together: Apply locks only after securing two desirable primary attributes, then resume rolling for secondary stats like Critical or Max HP.
Discard high-rarity off-class stats: Reroll gold-tier substats that provide no functional scaling for your class. Retaining an off-class roll makes later corrections significantly more expensive once enhancement levels are invested.

Leveling and Set Resonance

Distribute base enhancement materials across all equipped artifact slots rather than funneling resources into a single item.

Equip-wide thresholds: Artifact sets unlock resonance milestones when all equipped pieces reach designated level targets. Leveling an entire board evenly activates these shared multipliers at a lower total resource cost than maxing an isolated piece.
Offensive tier advancement: When spending high-rarity advancement stones for tier promotions, prioritize weapons and offensive slots first. Higher damage output speeds up PvE clear rates, securing the materials needed to upgrade remaining defensive pieces.

Resource Management for Secondary Accounts

When managing artifacts on secondary characters or resource-restricted accounts, adjust your spending criteria to avoid stalling overall progression:

Accept purple-tier rolls: Settle for high-percentage purple attributes that match your build rather than spending scarce refining locks chasing gold rolls.
Recycle duplicate pieces: Break down or feed redundant unequipped artifacts into your active pieces instead of spreading enhancement levels across multiple sets.
Leverage event shops: Acquire refining locks and upgrade bundles during server rebate events to minimize direct currency expenditure.
