Larrow Butz

The unlucky god-slaying bow hidden in the swamp.

Crazy God-Slaying Bow

I am lying in wait within the mud

Lore

It is said that in the center of Mysterious Swamp lives a zombie who has practiced archery for a long time. His archery is excellent, but bad luck follows him, hence the name Larrow Butz. He hides on the path to the Artifact not to worship Majorist, but to stop the foolish god who brings only curses of misfortune.

He predicts that Majorist will pursue the so-called Artifact, but his mission still fails. He says that he and the Doctor will be sung of for generations. In battle, though, he spends much of his time invisible and appears only to fire arrows, so his presence is a little intermittent.

Mechanics

Role

Area miniboss · Invisibility and blind volley

  • Appears briefly after the battle starts, then enters an invisibility cycle.
  • Each visible position is random, usually among the right-side columns.
  • After appearing, uses a blind volley, firing a ring of arrows. Higher difficulties increase the number of arrows.
  • The lower his health gets, the more volleys he fires during each visible window.
  • A stable formation, sustained damage, and good armor handling are more reliable than one burst of damage.

Advanced mechanics

Larrow Butz compresses invisibility, random positions, and arrow rings into short exposure windows. The player prepares while he is hidden, redirects fire when he appears, and keeps enough spare structure to survive blind volleys and add pressure.

Visibility cycle and damage window

Larrow Butz only takes stable damage after he has become visible enough. A hit during low-opacity invisibility is not the same as meaningful HP loss. This threshold rewards continuous coverage: if the formation starts searching for him only after he appears, much of the window is already gone.

The visible phase also has an internal damage buffer. Dealing enough damage inside the window can collapse the current exposure into a shorter exit segment; scattered damage lets him remain visible longer and gives later arrow rings their full timing. Damage is therefore both HP pressure and window control.

A160ΔH=D,A<160ΔH=0A\ge160\Rightarrow\Delta H=D,\qquad A<160\Rightarrow\Delta H=0
Appearance is not a fixed standstill; only the high-opacity window is a reliable damage segment.

Blind volley: HP gates and arrow rings

After the fight reaches its middle stretch or after enough cumulative damage, Larrow Butz starts adding blind volleys to his appearance cycle. Each ring spreads evenly outward from his position, with higher difficulty increasing the arrow count; from Easy to Unbalanced, it can be read as four to eight arrows per ring.

Low HP turns one exposure into multiple threats. Below half HP, a middle volley is added; below quarter HP, a later volley is added as well. Because the volleys overlap the damage window, greedy damage must be weighed against whether the formation has empty cells, pads, or replacements to absorb forced adjustments.

Narrows=d+4,θi=θ0+2πiNarrowsN_{\text{arrows}}=d+4,\qquad \theta_i=\theta_0+\frac{2\pi i}{N_{\text{arrows}}}
Difficulty determines arrows per ring; HP gates determine how many rings can occur in one exposure.

Random positions and stable formation

Visible positions do not queue by lane. Larrow Butz can reappear across several right-side and central areas, so single-lane burst setups miss too often. A safer plan keeps baseline damage across multiple lanes and treats each exposure as a repeatable small window.

The stage also uses buckets and regular enemies to pull fire away from the boss. If the formation can only start redirecting damage once Larrow appears, adds steal the window. If the front and flanks already handle ordinary pressure, the boss appearance can receive concentrated fire immediately.

  • Coverage line: give multiple lanes sustained reach instead of stacking all damage into one lane.
  • Front line: buckets and adds must be handled by the normal formation or they will steal exposure time.
  • Burst line: save Cherry Bomb and similar one-use damage for high-opacity windows with manageable volley risk.
Wide coverage turns random positions into repeated small windows instead of repeated target searches.
