The accepted Ais family rebuilds Magic ATK, resolves Magic DEF and penetration, applies the level coefficient and qualified modifiers, then evaluates critical, encounter, and cap stages for each event.
Rebuilt Magic ATK → Magic DEF and reduction → skill coefficient → Wind and target modifiers → conditional magic critical → encounter divisor → caps
Follow this order with the stats, skill level, target, and active modifiers from your own build. The exact example below proves the arithmetic for one supported setup; its final damage is not a target for another character.
Enter the values from your character, skill, and target. Results update as you type, stay in your browser, and are never saved.
Enter the totals from the build you use with the selected hero and attack. Action-specific, target-qualified, and Final Damage modifiers remain separate stages.
With these exact inputs: 202 damage per event; 404 total across two separately calculated events.
These probabilities apply only when every selected damage event rolls independently.
This calculator follows the ordering described on this page. Skill-specific rewrites and unsupported build lanes still require their own verified family support.
Level 170 Base Ais uses Symphony of Wind and Fire Lv. 10 with no equipment or active status changes. This is one verified critical event against Novice Bagg, shown to make every operation visible—not a recommended build or target damage number.

Each event runs the full calculation independently. Replace the shown inputs with your own when a supported family calculator is available; this verified result applies only to the Base Ais, skill level, target, critical state, and no-status setup shown here.
With the inputs shown below, Base Ais deals 202 critical damage per event with Symphony of Wind and Fire Lv. 10 against Novice Bagg. The skill produces two separately calculated events, for 404 total damage when both resolve against the same unchanged target state.
This example is Verified for Base Ais and level-170 stat-only Ais Ymir builds with no equipment or active status changes. Other builds should use their own Magic ATK, skill level, defense and penetration values, modifiers, critical state, and encounter inputs.
- Actor: Base Ais Wallenstein or a level-170 stat-only Ais Ymir build.
- Skill: Symphony of Wind and Fire, level 10.
- Target: Novice Bagg MVP baseline.
- Status changes: none active.
Intelligence 15 rebuilds Base Magic ATK to 17. Against 1,250 Magic DEF, the client chooses 0.166667 over the smaller 0.001045 defense branch. That leaves 2.833333 Magic ATK after defense.
The 12,000% level coefficient raises that value to 340. The Wind modifier reduces it to 85, and the non-Demi-Human NPC modifier raises it to 136. The client-order floating-point value lands just below 136, so the handler floor records 135.
The Magic DEF and Ignore Magic DEF lane is active, while Magic Penetration plus Enhance-converted Physical Penetration is zero in this example. Their place in the formula is verified, but they do not change this result beyond the shown Magic DEF multiplier.
Conditional magic critical multiplies the 135 handler result by 1.5, producing 202.5. The final floor records 202 uncapped damage, 202 displayed damage, and 202 Actual MVP HP removed for that event.
The second event repeats the same calculation. The verified total is 202 + 202 = 404, not one event multiplied before defense, modifiers, critical handling, or caps.
Other skill levels, equipment, non-attribute progression, active statuses, inherited copies, other skills, targets, encounter difficulties, and PvP need their own verified calculation support.
