Spark Corral

#Overview

Spark Corral is the evolution of Spud Fence, made by opening a chest with Spud Fence at level 8 and GPU owned. It uses the same fence logic: a post every 60 units Tibo moves, with damaging arcs between consecutive posts. What changes are the numbers: each zap deals 85 damage instead of 50, arcs are wider, more posts stand at once and each lasts much longer.

#How it works

The rules are the same as Spud Fence; here is what they work out to with Spark Corral's values.

• Posts. The limit is live (4) plus the extra Amount, capped at 8. Spark Corral's raw Amount of 4 gives 7 posts, and any +1 Amount, such as the one from GPU, reaches the cap of 8.^[1]
• Lifetime. Duration 9 with Tibo's base +25% means each post lasts 11.25 s, longer than the 9 s in the in-game description. At base move speed Tibo plants about one post per second, so the post limit, not the lifetime, usually decides how long the fence is: 8 posts make 7 arcs, about 420 units of wire when walking straight.
• Width. Area 2.25 makes each arc 54 units wide (27 on each side of the line), against 30 for a level 8 Spud Fence.
• Hit rate. Unchanged: a pest touching any arc is zapped at most once every 0.2 s, so 85 damage up to five times a second.

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): a pest touching the wire was zapped every 0.2 s (12 ticks) for 85. All three seeds gave the same figures.

#Tips

• With up to 8 posts you can walk a full loop around a group and close the fence on them; pests inside then cross an arc whichever way they move.
• Despite the GPU recipe, the fence ignores GPU heat: it neither builds heat nor slows down when the GPU throttles other weapons.

#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.

Evolutions have no level-ups in the game data; they use these fixed raw values.

#Obtaining

• Get Spud Fence to level 8 while owning GPU (any level), then open a chest. See Evolutions.
