Thunder Tuber

#Overview

Thunder Tuber is the evolution of Starch Bolt. It works the same way, striking random enemies around Tibo, but on a much larger scale: every 1.7 seconds it hits 9 different pests within 180 units (its raw amount of 8 plus the +1 base amount bonus every non-aura weapon gets, see Stats), each strike dealing 66 damage in a blast of 24 units around the target. A maxed Starch Bolt manages 7 strikes of 48 damage with 18-unit blasts every 2 seconds.

You get it by opening a chest while Starch Bolt is level 8 and you own Sprouting Eyes at any level. Thunder Tuber can still take part in the Starch Supercell union with a maxed Starch Chain. See Evolutions and Chests.

#How it works

The targeting rules are the same as Starch Bolt's: the weapon waits until an enemy is within range, then picks distinct random targets inside that circle, and all strikes land in the same instant. If fewer than 9 enemies are in range, the remaining strikes are skipped.^[1] Its catalyst also keeps paying off: every extra projectile from Sprouting Eyes is one more strike per cast. Since you need Sprouting Eyes to evolve, which gives +1 projectile from its first level, a fresh Thunder Tuber normally strikes at least 10 enemies per cast when that many are in range.

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; 12 pests held on a ring 75 units from Tibo): every 1.7 s exactly 9 pests were struck on the same tick, each for 66. All three seeds gave the same figures.

#Tips

• Thunder Tuber shines against dense waves, where all 9 strikes find targets and the 24-unit blasts overlap. Against a lone boss most of the cast is wasted, so keep a focused weapon for boss fights.

#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 Starch Bolt to level 8 while owning Sprouting Eyes (any level), then open a chest. See Evolutions.
