Report bugs and suggestions through Discord to: tnaab


Notes:
This calculator is a pure "copy" of rocalc, which was being updated by kurimet.
He gave me permission to download and modify rocalc to fit the changes done on Alfheim.
Reminder that the calculator is not 100% accurate to the results in-game. Use it as a guideline, but to test accurately, use the test server.
This was not made in collaboration with any GM's from Alfheim, so don't bug them if there's any errors.

• Fixed Adventurer's Revolver not being usable by Gunslinger/Night Watch.
• Fixed Lord of Vermillion autocast effect from Big Eggring Card not showing up under list of "Player Attack Skills".

(A) Changelog 2025-07-14
• Fixed minimum for soft DEF and soft MDEF being 0 instead of 1.
• Fixed Grand Cross/Dark Grand Cross formula:
  • Magic damage % cards now apply to the total damage, instead of just the MATK portion.
  • Elemental modifiers now apply twice, once before % modifiers, and once after.
• Fixed Stone Skin reducing soft MDEF instead of directly increasing magic damage.

(A) Changelog 2025-06-02
• Fixed Arrow ATK unintentionally being applied to minimum damage.
• In-game Arrow ATK is applied as rnd(0, Arrow ATK - 1), so for minimum damage 0 is considered.

• Fixed Spiral Pierce being affected by Spear Mastery.
• Fixed the STR bonus on Spiral Pierce being divided by 5.
• Adjusted the 3% damage increase on Spiral Pierce to a 6% damage increase, and moved the calculation to the correct place.
• Spiral Pierce's damage should now more accurately represent the damage in-game, with a 0~1% difference.
• Increased length caps on numbers in "Manual Edits on Player" and "Manual Edits on Enemy".
• Changed "Cast Time/Delay" under "Other Info" to "Cast Time/Cast Delay/ASPD%".
• "Cast Time/Cast Delay/ASPD%" now also displays total ASPD% and ASPD% from Impressive Rift, Gear, Skill, and ETC sources.
