PokéSurvivor Rift Arenas

The opening system uses a 30-second check countdown once the run is past 75 seconds. Consecutive eligible misses increase the next opening-roll chance by 20 percentage points. A successful opening roll resets that sequence. Each eligible check can open one portal; the rising chance does not set five fixed portal times.

A living regular boss blocks the next rift check without advancing its chance. An existing portal or an active arena also interrupts the normal check sequence, and new openings stop at minute 28. Even a 100% opening roll still needs the game to find a free location for the portal. Avoid interpreting the increasing chances as a guarantee that a portal will be visible every two and a half minutes regardless of the field state.

The legendary is selected first, then one of its types determines the arena. A dual-type opponent can therefore appear in different arena themes. The theme does not replace the opponent's defensive types: Articuno remains Ice/Flying in both Eternal Glacier and Sky Peak.

Arena weather can change the value of an otherwise useful attack. At full intensity, sun boosts Fire ×1.5 and halves Water; rain boosts Water ×1.5 and Electric ×1.2 while halving Fire. Snow boosts Ice ×1.5 and slows non-Ice partners by 10%. Sandstorm boosts Rock, Ground and Steel attacks ×1.3; those partner types also avoid its chip damage. Fog boosts Ghost, Fairy and Psychic attacks ×1.3.

PokéSurvivor changes main-series matchups to ×1.6 for a weakness, ×0.6 for a resistance and ×0.3 for an immunity. Multiply both contributions against a dual-type opponent, then clamp the type result to ×0.3–×2.4. Two weaknesses produce ×2.4 after the cap rather than the raw ×2.56.

Articuno shows why the second type matters. Rock is strong against both Ice and Flying, reaching the cap. Fighting is strong against Ice but resisted by Flying, so its combined type factor is ×0.96. Ground against Fire/Flying Moltres combines ×1.6 and ×0.3 for ×0.48. Electric against Ground Groudon still deals ×0.3 type damage, rather than zero. These examples exclude weather, move strength and partner upgrades.

Look up the legendary before planning a specific hunt, then check which attacks your partner can actually learn. Switch to an appropriate learned move during the fight. An arena's Fire or Ice label alone is not enough to decide your best attack against a dual-type boss.

During an ordinary arena, field enemies are stored and normal spawning pauses. The fight takes place inside a bounded arena, and the legendary collides with its walls and columns. Keep a clear line for your attacks while moving around the obstacles; letting a column sit between you and the opponent can waste part of the combat window.

The opponent's HP grows with run time: round((3200 + run seconds × 9) × player-count HP factor × multiplayer arena factor). The player-count factor is 1 + 0.3 × (N − 1), and the arena factor is ×1.4 for a group of two or more. For four players, the combined factor is ×2.66 compared with solo at the same run time. This HP formula does not predict your clear time.

A victory gives a short reward interval before returning. A failed arena sends you back without its victory reward; a fallen local player is revived at 30% maximum HP on return. The stored field enemies resume afterward, so the transfer does not erase the horde you left behind. In co-op, allow teammates time to regain their position before continuing.

Each ordinary rift victory grants a Bond. A Bond combines learned moves into one active group: begin with two separate moves, then add eligible loose moves to the existing group up to four. You need suitable learned moves for a fusion option; owning a Bond alone does not supply a new attack or a new Pokémon. In co-op, fusion choices pause the group until the players finish.

Defeating an ordinary, non-shiny legendary does not directly add its normal partner to your collection. Use the appropriate regional gacha for that acquisition route. A shiny-capable legendary has a 1-in-512 shiny roll when the rift opponent is selected, and defeating a shiny enemy unlocks its shiny partner form. Entering an arena or seeing a shiny is not the defeat required for that unlock.

An opponent you have not yet defeated has selection weight 4; one already defeated has weight 1. This favors new encounters but does not prevent repeats or guarantee a specific missing legendary next. Rift arena victories and unique legendary defeats are also different achievement targets: winning the same type arena again cannot fill a missing arena type.

Judgment begins when the run reaches 30 minutes. If you are still in a rift or choosing a level-up card, the transition waits until that activity finishes. Arceus is invincible and is not an attack target. Prioritize movement and the ground warnings while attacking the damageable legendary summons when you have an opening.

Legendary summons arrive every five seconds. Each successive summon has twice the HP and damage of the preceding one, so pressure increases even if your build handled the first opponent. They give XP but no coins, tickets or items. Judgment has no fixed survival time limit and no ordinary-rift victory condition; the aim is to extend the attempt.

Arceus pursues players faster as the fight continues. His contact and warned attacks use maximum-HP percentages and ignore type and defense. Read the hazards below as movement priorities. Reaching Judgment, lasting another 60 seconds and defeating three summons in one Judgment are separate achievement goals; summon defeats do not substitute for ordinary rift legendary records.
