Use this page before first attempts on Major Miner, then return after a few pulls to refine punish windows.
Pair it with a defensive setup if you are still learning movement, or a damage setup once the pattern is familiar.
Use the notes as a route checkpoint when deciding whether to spend Bones before continuing.
Treat the first few attempts as scouting pulls: learn one safe answer per attack before chasing full damage rotations.

Fight notes belong with Bone Beach.
Suggested order context: Major Miner is tracked as mini-boss #7 in the current route data.
Reward details should be verified in-game before planning a strict completion route around them.

Test safe openings first: one attack, reposition, then repeat until the recovery window is obvious.
Watch for room hazards and approach lanes before judging the weapon matchup.
Keep exact damage numbers flexible because patches, upgrades, and modifier settings can change the feel of the fight.

Greeding long combos after the first safe hit instead of resetting spacing.
Entering with a route loadout when the fight needs a boss-specific defensive or damage setup.
Ignoring the nearest Underlab and losing resources to repeated runbacks.
Changing too many loadout pieces between pulls, which makes it harder to tell whether the improvement came from routing, spacing, or raw stats.
