Optimizing DPS with the Skillchain Calculator
In high-level MMO and RPG combat mechanics, mastering the Skillchain (or Resonance) system is often the difference between a timed victory and a wipe. This Skillchain Calculator is designed to help players estimate the burst damage generated when two or more weapon skills interact elementally.
What is a Skillchain?
A Skillchain occurs when a player executes a "Closing" Weapon Skill (WS) within a specific time window after an "Opening" WS, provided the elemental properties align. The resulting resonance deals immediate elemental damage based on the closing skill's power.
How the Calculation Works
While specific formulas vary by game (e.g., FFXI, classic RPGs), the core logic typically follows a scaling multiplier system:
Closing WS Damage: The raw damage dealt by the final attack in the combo. The Skillchain damage is calculated as a percentage of this value.
Tier Level:
Level 1 (e.g., Scission): Usually deals ~50% of the closing WS damage.
Level 2 (e.g., Gravitation): Usually deals ~60% of the closing WS damage.
Level 3 (e.g., Light/Dark): Can deal 100% or more of the closing WS damage.
Chain Step: The longer the chain (Step 2 vs Step 5), the higher the damage multiplier typically scales.
Resistance: If an enemy resists the elemental type of the Skillchain (e.g., using Fire against a Fire Elemental), the damage is reduced by the resistance percentage.
Maximizing Your Burst Windows
To get the most out of this calculator and your in-game performance, consider the following strategies:
1. Align Elemental Weaknesses
A Level 3 Light Skillchain effectively doubles your damage output, but if the boss has 50% Light Resistance, a Level 2 Gravitation (Earth/Dark) chain might actually yield higher numbers. Use the "Target Resistance" field in the calculator to check these scenarios.
2. Stack "Skillchain Damage +" Gear
Many games offer equipment sets that provide a specific "Skillchain Damage +%" bonus. This is a final multiplier. If you have +20% from gear, a 1000 damage chain becomes 1200. This scales aggressively with high-damage closing skills.
3. Don't Break the Chain
Advanced chains (Steps 4, 5, and 6) often provide diminishing returns on the multiplier but allow for continuous damage pressure. Use the "Chain Step" dropdown to see how extending a combo from a 3-step to a 4-step affects your total damage throughput.
Frequently Asked Questions
Does the Opening Weapon Skill damage matter?
Generally, no. The resonance damage is calculated strictly based on the Closing Weapon Skill. However, the opener is vital for establishing the elemental window.
What happens if the target fully resists the element?
If the target has 100% resistance or absorption to the element, the Skillchain will deal 0 damage or potentially heal the target. Always verify elemental affinities before committing to a long chain.

"acceptedAnswer": {
"@type": "Answer",
