Suggested order context: Radiant Lionel is tracked as boss #12 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.
