What Does It Do?
Most calculators show you stats — SWLens simulates actual combat damage. The Artifact DMG Calculator takes your monster's full stat profile, selects any skill from the game data with its real multipliers, and simulates the exact damage that skill would deal under the battle conditions you configure. It factors in everything the game considers: your monster's stats, skill multipliers, artifact sub-properties, enemy defense and HP, buffs, debuffs, glory towers, guild flags, leader skills, elemental advantage, passives like
Deborah's Blacksmith's Discernment passive, and more.
The result? Exact damage numbers — crit damage, non-crit damage, average damage per hit, and total damage across all hits. In-game damage has a small random variance, so the calculator shows the expected average with actual results falling within approximately ±5% of the calculated value.
But the real power isn't just seeing damage numbers — it's the automatic artifact ranking. After configuring your battle scenario, the calculator tests hundreds of artifact combinations from your entire inventory and ranks the best pairings by damage output. You'll know exactly which artifacts to equip for maximum damage — no guesswork.
Monster & Skill Selection
Select any monster from your imported SWEX JSON collection. The calculator automatically loads all skills from the game data — complete with their real damage multipliers. Switch between S1, S2, S3, and S4 to see how each skill performs under the same battle conditions.
Real Skill Multipliers
Every skill's damage formula is loaded directly from the game data. ATK-scaling, HP-scaling, DEF-scaling, SPD-scaling, and hybrid formulas — all handled automatically.
Skill-Ups Included
Skill level bonuses are read from your JSON data. See the actual damage your monster deals at its current skill-up level, not just theoretical max.
Multi-Hit Support
Skills that hit multiple times show damage per hit AND total damage across all hits. The artifact ranking uses total damage for accurate comparisons.
Stat Override Mode
Want to theorycraft? Override any stat manually to test hypothetical builds. See how much damage you'd deal with 50 more CD or 1000 more ATK.
Battle Configuration
This is where the calculator truly separates itself from anything else available. Configure the exact combat scenario you want to simulate — down to the specific enemy, their stats, active buffs and debuffs, tower levels, and even enemy artifact damage reduction.
Enemy Stats
Set the enemy's DEF, Max HP, current HP%, and element. You can enter values manually for PvP scenarios, or select a specific enemy unit from your JSON inventory. The element selection unlocks elemental advantage calculations — when your monster has advantage, the calculator automatically applies the +15% Critical Rate bonus. You can also test against ALL elements to see average damage across all matchups.
Enemy DMG Reduction Artifacts
In PvP, your opponent's artifacts may have “DMG from [Element]-” sub-properties that reduce your damage. The calculator lets you input these per-element reductions so you see realistic PvP damage, not just raw numbers.
Dungeon Presets
Want to know exactly how much damage your
Lushen deals to the Giants B12 boss? Or whether your
Kro can one-shot
Zaiross in Dragons B12? The dungeon presets make it effortless.
Click any dungeon to expand its waves, then click any enemy portrait to instantly load their exact stats — DEF, HP, element, and boss status. Every wave is covered:
Crystal (Pure), Water Golem, Kuhn (Mini-Boss), Water Golem, Crystal (Pure), Water Golem, Ancient Giant (Final Boss)
Small Crystal, Medium Crystal, Zaiross (Mini-Boss), Small Crystal, Medium Crystal, Abyssal Dragon (Final Boss)
Crystal (Pure), Dark Golem, Grego (Mini-Boss), Crystal (Pure), Dark Golem, Ancient Lich King (Final Boss)
This is invaluable for speed team optimization. Instead of guessing whether your monsters can clear waves fast enough, you see the exact numbers — and can test which artifact pairings push you over one-shot thresholds.
Buffs, Debuffs & Combat Modifiers
Real combat involves buffs and debuffs — and the calculator models all of them:
Buffs (on your monster)
ATK Buff — increases your effective attack power
DEF Buff — factors into DEF-scaling skill damage
SPD Buff — factors into SPD-scaling skill damage and artifact interactions
Debuffs (on the enemy)
DEF Break — dramatically reduces enemy defense, massively increasing your damage
Branding — enemy takes 25% more damage from all sources
Special Passives
Some monsters have passives that change how combat mechanics work. The calculator supports these — for example,
Deborah's passive increases the decreasing effects of ATK, DEF, and SPD that enemies receive by 30% (15% for bosses). The calculator applies the correct enhanced reduction automatically.
Passive: Blacksmith's Discernment — Increases the decreasing effects of Attack Power, Defense, and Attack Speed that enemies receive by 30% (15% if it's the boss). The calculator applies the correct bonus automatically.
Other Combat Modifiers
- Ignore DEF — full (100%) or partial percentage for ignore-defense skills
- First Attack bonus — for “First Attack CD+” artifact sub-properties
- CR Override — force a specific crit rate for comparison testing
- CD Reduction — simulate enemy artifacts that reduce your crit damage
Leader Skill ATK% — apply arena/guild leader skill bonuses- Fight Sets — stack ally Fight set bonuses (8% ATK per set)
Glory & Guild Towers
Tower bonuses significantly affect damage calculations — and most other calculators ignore them. SWLens includes every Glory Tower and Guild Flag:
Guild Flags add HP (5%), ATK (5%), and DEF (5%) bonuses on top. Click “Max Towers” to instantly set all towers to maximum — or configure each one individually to match your current tower levels. In PvP scenarios, towers affect both your stats AND enemy stats for accurate simulation.
Artifact Ranking & Recommendations
This is the killer feature. After configuring your battle scenario, the calculator automatically scans your entire artifact inventory and ranks every possible pairing by actual damage output — not just stat numbers, but real simulated combat damage.
Two-Tier Ranking System
Top 5 element artifacts and top 5 type artifacts ranked independently. Each shows the damage difference vs your currently equipped artifact.
Top 3 combined pairs (element + type together). Tests thousands of combinations to find the absolute best pairing — because the #1 element artifact + #1 type artifact isn't always the best pair.
Each recommendation shows the artifact icon, grade, all sub-properties, and the exact damage difference — in both absolute numbers and percentage. Green means an upgrade, red means a downgrade. You'll know instantly which artifacts to swap.
Locked Artifacts
Found the perfect artifact pair for a monster? Lock it. Locked artifacts are excluded from rankings for all other monsters — preventing the calculator from recommending the same artifact to multiple units. This lets you work through your monster box one by one, locking the best pairs as you go.
- Lock pairs — click the lock button on any recommended pair to reserve it
- LOCKED tab — view all locked pairs across all monsters in one place
- Unlock — remove individual locks or unlock everything at once
- Persistent — locked pairs are saved in your browser and persist across sessions
Understanding the Damage Output
The results panel shows a side-by-side comparison of your currently equipped artifacts vs any recommended pair you're previewing:
- Crit Damage — damage per hit when you land a critical strike
- Non-Crit Damage — damage per hit without a critical strike
- Average Damage — expected damage per hit accounting for your crit rate
- Total Damage — average damage × number of hits for multi-hit skills
- Additional True Damage — bonus damage from artifact effects like “Addl. DMG by ATK” that bypasses defense
- Grand Total — the final number used for all artifact ranking comparisons
When previewing a recommended pair, the difference is shown in both absolute numbers and percentage — e.g., +5,234 (+12.3%) for an upgrade.
Frequently Asked Questions
How accurate is the damage calculation?
The calculator matches in-game damage within approximately ±5%. Summoners War applies random variance to every hit, so the calculator shows the expected average damage. Your actual in-game results will fluctuate within this range.
Does it consider all artifact sub-properties?
Yes — CD+, Additional DMG by ATK/HP/DEF/SPD, elemental damage bonuses, buff effect enhancers, conditional CD+ (HP Good/Bad), single target CD+, first attack CD+, counter/co-op DMG+, and more. Every artifact sub-property that affects damage is factored in.
Can I test damage against specific dungeon bosses?
Yes. One-click dungeon presets for Giants B12, Dragons B12, and Necro B12 let you select any enemy from any wave — mini-bosses, crystals, golems, and final bosses — with their exact stats pre-loaded.
How does artifact ranking work?
The calculator tests your entire artifact inventory across thousands of possible pairings. It ranks both individual slot candidates (top 5 per slot) and the best combined pairs (top 3), showing the exact damage difference compared to your currently equipped artifacts.
Does it support HP/DEF-scaling monsters?
Yes. Skill multipliers are loaded directly from game data and support all scaling types — ATK-based, HP-based, DEF-based, SPD-scaling, and hybrid formulas like Beast Monks (HP + ATK scaling).
What about passives like Deborah’s?
Supported. The calculator applies the correct passive bonuses — for example, Deborah’s passive amplifies DEF Break beyond the standard amount, with different values for normal monsters vs bosses.
Can I lock artifacts to specific monsters?
Yes. Lock artifact pairs to specific monsters so they’re excluded from rankings for other units. This prevents the calculator from recommending the same artifact to multiple monsters. Locked pairs persist across sessions.
Does elemental advantage affect the calculation?
Yes. When your monster has elemental advantage, a +15% Critical Rate bonus is automatically applied. You can calculate damage against ALL elements or filter by specific matchups to see how damage changes.
