Build direction

Eternatus starts with Sludge, a Projectile attack. Build the early run around this actual starting behavior, then choose alternatives from its legal pool.

Start at range and align enemies for the projectile path. Projectile count is emitted shots, not guaranteed hits on a boss.

Strengths & limits from its stats

Base HP 133 versus dataset median 99; movement 133 versus 105; attack multiplier ×1.5 versus ×1.17. Medians use all 966 entries and describe base stats, not win rates.

Its HP is at or above the dataset median, giving a larger base health buffer than lower-HP entries; this does not remove type weaknesses or incoming warnings.

Movement is at or above the median, which helps repositioning under equal modifiers. Liquids, snow and traps can still reduce effective speed.

Move choices & active slots

Its regular learn pool contains 14 moves across 9 behavior families. Choose a different behavior or attack type for a real target problem; learning extra ordinary slots does not add simultaneous damage.

For a different damage pattern, inspect Toxic / Toxic Spikes. These are legal alternatives from its pool; compare their level, evolution and target conditions before replacing the active attack.

Upgrade & evolution route

A practical first budget shortlist is Reflexes / Critical Hit, based on the stat comparison above. Compare costs and your actual failure point; these are recommendations, not a universally optimal purchase order. Permanent levels belong to this Pokémon.

For Sludge → Sludge Bomb, reach move level 5, take the Power card in this run and select the evolution offer. Buying a similarly named permanent upgrade does not satisfy that condition.

This analysis is derived from the displayed source stats and combat rules. It does not claim playtesting, measured win rate or guaranteed run length.

Shiny

Shiny	Details
Shiny sprite available	Yes
Gacha generation	1/100
Rift legendary selection	1/512

These are generation odds for an eligible source, not a guaranteed capture. A wild or rift shiny must be defeated to join the collection; gacha also applies its collected-shiny re-selection rule.

Legendary rifts

After 75 seconds, valid checks occur every 30 seconds with 20%, 40%, 60%, 80% and 100% conditional chances. A live boss skips a check; existing portals and arenas also change eligibility.

Unbeaten legendaries have weight 4; beaten ones have weight 1. The selected legendary chooses one of its types for the arena.
