Summoners War Rune Retention and Reappraisal Guide

To keep your rune inventory manageable and progress efficiently in Summoners War, evaluate every rune drop by substat synergy rather than grade alone, and reserve Reappraisal Stones strictly for six-star Legend runes on high-impact sets. A purple Hero rune with fully aligned, grindable percentage stats regularly outperforms an orange Legend rune scattered with incompatible flat values.

Rune Retention Filters and Upgrading Rules

When evaluating drops from Cairos Dungeon farming, test runes up to +6 or +9 to see how their substats distribute. Sell any piece that fails to hit complementary rolls or scatters upgrades across conflicting roles.

• Speed-Contested Runes: Roll Swift, Despair, and Violent runes that show base Speed up to +6. If they fail to roll Speed consecutively, sell them unless the rolls land in high percentage values suited for tank or damage builds.
• Bruisers and Tanks: Keep runes with combinations of HP%, DEF%, and Resistance on defensive sets such as Will, Nemesis, and Violent. Runes lacking Speed remain viable if their combined effective health stats hit near-maximum rolls.
• Damage Dealers: Look for Attack%, Critical Rate, and Critical Damage clustered together. Discard offensive runes lacking Critical Rate unless they fit specific niche units, such as bombers or monsters whose damage scales entirely from defense or speed.
• Immediate Sells: Instantly sell runes featuring flat Attack, flat Defense, or flat HP as primary substats alongside conflicting stats, as these dilute overall monster efficiency.

Even-Slot vs. Odd-Slot Retention Standards

Odd slots (1, 3, and 5) feature fixed main stats, making high-synergy substats far easier to acquire over time. Maintain strict keep thresholds for odd slots, preserving only pieces that roll near-maximum values in designated roles.

Even slots (2, 4, and 6) govern percentage scaling and slot 2 Speed. Because matching the correct main stat to the correct set is rare, keep standards can be slightly more flexible during initial rolling.

Evaluating Non-Speed Rolls and Stat Density

Not every competitive rune requires high base Speed. Triple or quadruple rolls into HP%, Defense%, or Attack% create massive stat density suitable for turn-two compositions, Guild Siege defenses, and PvE farming teams.

A rune that rolls high values across three synergistic percentage stats is an ideal candidate for an Enchanted Gem to add Speed later. Discard missed Speed rolls only when the upgrades land in minimum values or scatter into mismatched archetypes.

Reappraisal Stone Allocation Rules

Reappraisal Stones are among the most limited resources in the game. Apply them using the following restrictions:

1. Never Reappraise Hero Runes: Only use Reappraisal Stones on six-star Legend runes.
2. Prioritize High-Impact Sets: Focus reappraisals on Violent, Swift, Despair, and Will sets.
3. Target Even Slots First: Prioritize Slots 4 and 6 with HP%, Attack%, or Critical Damage main stats. Rerolling a rare main stat on an even slot provides higher account value than rerolling an odd slot that drops frequently.
4. Leverage Innate Prefix Stats: Target Legend runes that feature an unchangeable innate prefix stat. Because the innate stat cannot appear in the substat pool, innate Resistance, Accuracy, or flat stats permanently block unwanted properties from rolling into your primary substats.

Inventory Maintenance and Selling Traps

To keep your storage clear and mana reserves intact, conduct regular inventory cleanups:

• Sell Project Runes: Discard partially upgraded runes sitting at +3 or +6 that require two Enchanted Gems to become usable. A rune must require at most one gem modification to warrant retention.
• Purge Flat Main Stats: Sell all slot 2, 4, and 6 runes with flat HP, flat Defense, or flat Attack main stats. The only situational exception is a Swift slot 4 or 6 rune rolling pure Speed upgrades for early-turn contest units.
