**Thunder Tuber** is an evolution in tibo.dog. In-game description: “A storm of starch lightning.”

## Overview

Thunder Tuber is the evolution of [Starch Bolt](/weapons/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](/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](/passives/sprouting-eyes) at any level. Thunder Tuber can still take part in the [Starch Supercell](/weapons/starch-supercell) union with a maxed [Starch Chain](/weapons/starch-chain). See [Evolutions](/evolutions) and [Chests](/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. [sim-BkfBhQfw.js: `for(let o=0;o<r.amount;o++){let o=Yo(e,n.range,i);if(o===void 0)return;`] 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](/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.

| Stat | Value |
|---|---|
| Damage | 66 |
| Cooldown (s) | 1.7 |
| Amount | 8 |
| Area | 2 |
| Speed | 0 |
| Duration (s) | 0 |
| Pierce | 0 |
| Knockback | 0.6 |
| Interval (s) | 0.1 |

### Behaviour parameters

## Obtaining
