Notes

Find your best next Artifact upgrade: enter your current stats and Artifact levels, and the green row shows which upgrade gives the most stages per Ancient Bar right now. In Idle Sword Master this edge plays out over several runs and updates - not always instantly after one click.
Attack Range is intentionally not included — there's no reliable way to convert ATR into a DPS value. Just buy it when it feels cheap. (fierywind)
This is a DPS-optimization aid, pair it with judgement: SSL becomes more valuable as you approach a 20-SSL milestone, so a short-term deviation can be worth it.
"AB per Stage Gained" is a comparison metric (Ancient Bars needed per stage of progress) — NOT the in-game purchase price of the next level.
"Skill SSL Level" = the Sword Spawn Level from your Sword skill (Skills tab) — not your Max Sword Level and not the SSL artifact.
