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.
