Butter Streak

#Overview

Butter Streak is a dash weapon: instead of firing on a timer, it lays a strip of melted butter along the path of every dash Tibo makes. The strip is a row of small damaging pools that hit every pest standing in them every 0.3 s and halve their movement speed for 1 s. At level 1 each strip lasts 2.5 s (2 s plus Tibo's base +25% duration) and hits for 9; by level 8 it lasts 3.75 s, hits for 28 and its pools are 30% wider.

It also works without dashing. Whenever its 2.5 s cooldown is ready and Tibo is walking, it drops a strip behind him. Butter Streak is offered on level-up cards; it is not in the pool of random starting weapons. At level 8, a chest opened while Tibo holds Spud Sneakers evolves it into Ghee Glide (see Evolutions).

#How it works

• Every dash places a strip, even if the cooldown is still running, and each dash restarts the cooldown.^[1] The strip runs from where the dash started along the dash direction, covering the full 48-unit dash (see Controls).
• Between dashes, when the cooldown is ready and Tibo is moving, a strip of the same length is laid backwards from Tibo's position, along the path he just walked.^[2] Standing still does not trigger it.
• Strip shape: the strip is made of ceil(48 / pool radius) + 1 circular pools spaced evenly along the path. Each pool has radius size × area (9 at level 1), so a level-1 strip is 7 overlapping pools.^[3]
• Hits: each pool ticks every 0.3 s (hitInterval). All butter pools of this weapon share one re-hit timer per pest, so a pest standing where pools overlap is still hit only once every 0.3 s.^[4]
• Slow: each hit sets the pest's speed to ×0.5 for 1 s, scaled by Tibo's duration stat. The pool's lifetime also scales with duration (see Stats).
• The in-game text says the butter "burns" pests for 2 s. In the data that is the strip's own damage over its 2 s raw lifetime; Butter Streak applies no separate burn status, only the slow.
• Extra projectiles (amount) place extra strips in the same spot at the same moment. Tibo's base +1 amount already makes every firing two identical strips. Because of the shared re-hit timer the extra strips add no damage.

Measured in the headless sim (tools/play.mjs, build 41 main-B2gf34bA.js, Standard, Normal, god mode, seeds s1, s2 and s3; the seeded starting weapon removed, the weapon given with give, spawning stopped after 4 s of play and the pests already on the field held at fixed spots with 10⁹ HP; Tibo walking right for 8 s past 12 pests held at fixed points on his path, no dashes): every 2.5 s it laid 14 pools at once at level 1 (two strips of 7, radius 9), each with a 2.5 s lifetime, and a pest on the strip was hit every 0.3 s for 9; at level 8 it laid 12 pools (two strips of 6, radius 11.7) with a 3.75 s lifetime, hitting for 28. Dash strips were not measured. All three seeds gave the same figures.

#Tips

• Damage depends on dash frequency more than on the 2.5 s cooldown. Dash charges and dash cooldown from Butter Socks mean more strips.
• Dashing through or along a crowd puts the strip under the pests, and the slow keeps them in it. Dashing straight away from a chasing group leaves the strip between you and them.
• Projectile-count passives do nothing for this weapon; area and duration help it.

#Stats

Values are the raw numbers from the game's definitions, before Tibo's global stat multipliers, difficulty and time scaling. In play, Tibo's base stats add +1 amount to every weapon except aura, cone, nuke and ring weapons, and make every duration ×1.25 (see Stats). Field names in code are the game's internal names. Attack descriptions such as “Melee slash” are this wiki's summary of the internal attack kind.

#Level progression

Each level-up adds the listed change to the weapon's raw values. Totals are cumulative.
