Notes

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.
"Cost per 1 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.
