Spoils of the fight

This page belongs to the Septemburg boss set and helps anchor the region's corrupted field route.

Best use cases

  • Use this page before first attempts on Patchling, 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.
  • If the fight blocks progression, favor repeatable survival over a faster clear; route consistency is the value this page should protect.

Route notes

  • Fight notes belong with Septemburg.
  • This boss is better treated as a local route gate than a standalone DPS check.
  • Reward details should be verified in-game before planning a strict completion route around them.

Tested notes

  • 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.

Common mistakes

  • 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.
