Roblox Abyss features 16 distinct races at launch, each granting unique stat bonuses and passive abilities that shape your underwater fishing experience. The race system directly impacts oxygen management, damage output, weight capacity, and survival in deeper biomes. Choosing the right race and understanding reroll mechanics can significantly improve progression through the game's challenging depths.
Quick answer: Kraken is the best race in Abyss, offering +20% Weight, +15% XP, +15% Cash, and two powerful passives: Endless Depths (stacking damage up to +50%) and Leviathan's Legacy (full oxygen regeneration on death with AoE damage). Shark ranks as the strongest Legendary race with +20% damage and oxygen-efficient tube boosts.
Race Tier List: S-Tier (Mythic)
Two Mythic races currently exist in Abyss, both with 0.2% standard reroll chance (1% with Lucky Reroll). These races provide the highest stat bonuses and game-changing passives that trivialize many late-game challenges.
Kraken stands as the undisputed best race. Its +20% Weight bonus exceeds all other races, while +15% XP and +15% Cash accelerate progression. The Endless Depths passive grants +0.04% damage per fish caught, capping at +50% after 1,250 fish—a permanent scaling buff that grows throughout your playthrough. Leviathan's Legacy functions as a second life: when oxygen depletes completely, you instead regenerate 100% oxygen and deal 300% AoE damage around your character. This ability has an 8-minute cooldown but can save critical deep-sea expeditions when oxygen runs low unexpectedly.

Sea Angel occupies the second Mythic slot. Specific passive abilities and stat bonuses for Sea Angel remain unconfirmed at release.
Race Tier List: A-Tier (Legendary)
Legendary races have a 2% standard reroll chance (10% with Lucky Reroll). These races offer specialized niches and perform nearly as well as Mythics in focused builds.
Shark delivers the highest raw damage in Abyss with +20% damage and -0.4 seconds cooldown (faster attack speed). Blood Frenzy activates when oxygen drops below 30%, granting an additional +30% damage—effectively +50% total damage in clutch situations. Sea Sprint reduces tube boost oxygen consumption by 50%, making emergency returns to the bubble far more forgiving. This combination makes Shark the premier damage race and a strong alternative if Mythic rerolls prove unsuccessful.

Vampire Squid provides +20% Oxygen (the highest oxygen bonus in the game), +10% XP, and Blood Siphon. Blood Siphon regenerates oxygen equal to 10% of damage dealt when catching fish, with a 15-second cooldown. Optimizing fish catches around this cooldown can extend underwater time almost indefinitely. However, Blood Siphon's current cooldown and regeneration rate make it less impactful than Shark's offensive toolkit.

Race Tier List: A-Tier (Epic)
Epic races have a 2% standard reroll chance (10% with Lucky Reroll). Crab stands out as the only Epic race worth keeping long-term.
Crab grants +15% Oxygen, +10% Weight, +10% Damage, and Iron Shell. Iron Shell has a 25% chance to absorb incoming attacks completely, negating all damage from that hit. This passive provides both effective damage reduction and safety against aggressive fish in deeper zones. Crab's balanced stat spread makes it viable for most playstyles.
Anglerfish offers -0.2 seconds cooldown, +5% Cash, Hunter's Instinct (10% chance for double drops when catching fish), and Abyssal Light (illuminates surroundings in darkness). Abyssal Light functions as a utility passive for dark biomes, making Anglerfish useful as a secondary race slot for exploration. Its stat bonuses lack focus compared to Crab.

Race Tier List: B-Tier (Rare)
Rare races have a 14% standard reroll chance (38% with Lucky Reroll). These races work adequately for early-to-mid game but should be replaced when better options become available.
Spirit provides -0.1 seconds cooldown, +5% Cash, and Last Breath. Last Breath regenerates 30% oxygen after death instead of dying, with a 3-minute cooldown. This passive helps newer players survive while learning oxygen management and biome layouts.

Puffer grants +15% Oxygen and Spiky Body. Spiky Body reflects 20% of incoming melee damage back to attackers, functioning as both damage reduction and a passive damage source. The reflection triggers on every melee hit (100% uptime), making Puffer surprisingly effective against melee-focused fish.

Narwhal offers +8% Speed, +15% Weight, and Piercing Horn (10% chance to deal double damage). The speed bonus improves both exploration and emergency escapes. Piercing Horn's 10% proc chance proves too inconsistent for reliable damage increases.
Race Tier List: C-Tier (Uncommon)
Uncommon races have a 29% standard reroll chance (27% with Lucky Reroll). Reroll these immediately if resources allow.
Cyclops provides +10% Damage. This flat bonus has value early but lacks the scaling or utility of higher-tier races.

Monkey grants +10% Speed and +5% XP. Speed helps with early oxygen constraints, and the XP bonus accelerates initial leveling.

Fish offers +5% Speed and +10% Weight. This race provides minimal impact even for beginners.
Race Tier List: D-Tier (Common)
Common races have a 50% standard reroll chance (3% with Lucky Reroll). These races should always be rerolled. Lucky Rerolls reduce Common race pulls from 50% to 3%, making them essential for efficient rerolling.
Human has no passive abilities or stat bonuses. This is the default starting race.
Elf grants +5% Speed. The bonus is negligible.
Poop provides +5% Damage. The stat bonus is too small to justify keeping.
Coral offers +5% Oxygen. This bonus does not meaningfully extend underwater time.
How to Reroll Your Race
Abyss uses Star Shards as reroll currency, earned through completing quests and achievements. Regular rerolls cost 100 Shards per attempt. Lucky Rerolls cost 450 Shards but drastically improve odds for higher-rarity races.
Step 1: Enter the bubble (hub area) and locate the race icon in the top-middle section of the screen. Click this icon to open the race reroll interface.
Step 2: Select either Regular Reroll (100 Shards) or Lucky Reroll (450 Shards). Lucky Rerolls increase Mythic race chances from 0.2% to 1% and reduce Common race pulls from 50% to 3%.
Step 3: Confirm the reroll. Your new race immediately replaces the previous race in that slot. Each character has two race slots, allowing you to keep one race for combat and another for utility (such as Anglerfish for Abyssal Light or Goblin for shop discounts).
Reroll confirmation appears as a visual change to your character model and an updated race icon. Check the race icon to verify the new race and its passive abilities.
Race Reroll Strategy
Save Star Shards for Lucky Rerolls rather than spending on regular rerolls. The 5x improvement in Mythic odds (0.2% to 1%) and dramatic reduction in Common pulls (50% to 3%) justify the 4.5x cost increase. Regular rerolls waste Shards due to the 50% chance of pulling unusable Common races.
Prioritize your primary race slot for combat-focused races (Kraken, Shark, Vampire Squid, Crab). Use the secondary slot for utility races like Anglerfish (Abyssal Light for dark biomes) or races with non-combat passives. If you pull a strong Legendary race like Shark, consider keeping it rather than burning all Shards chasing the 1% Mythic rate.
Quests and achievements provide the most reliable Shard income. Most daily quests reward 10-20 Shards. Focus on completing these consistently rather than attempting to farm Shards through other methods.
Race Passive Mechanics
Passive abilities trigger automatically without player input. Kraken's Endless Depths accumulates damage permanently as you catch fish—progress persists across sessions and does not reset. Leviathan's Legacy activates only when oxygen reaches zero, not when health depletes from fish attacks.
Shark's Blood Frenzy checks oxygen percentage continuously. The +30% damage bonus applies immediately when oxygen drops below 30% and deactivates when oxygen rises above that threshold. Sea Sprint's 50% oxygen reduction applies to tube boost consumption, not passive oxygen drain.
Vampire Squid's Blood Siphon triggers on successful fish catches, not on fish attacks. The 15-second cooldown begins when the ability activates, not when oxygen is consumed. Timing catches around this cooldown maximizes oxygen regeneration.
Crab's Iron Shell has a 25% independent chance per incoming attack. Multiple attacks in quick succession each roll separately. The ability negates all damage from absorbed hits, including damage-over-time effects applied by that attack.
Spirit's Last Breath triggers only when oxygen depletes completely, not when health reaches zero from combat damage. The 3-minute cooldown begins when the ability activates. If you die again within 3 minutes, Last Breath will not trigger.
Race Synergies with Equipment
Shark pairs well with fast-attacking harpoons due to its -0.4 seconds cooldown bonus. The cooldown reduction stacks additively with weapon cooldown stats, resulting in higher overall DPS. Blood Frenzy's low-oxygen damage bonus synergizes with aggressive deep-diving playstyles that intentionally push oxygen limits.
Vampire Squid works best with high-damage harpoons that maximize Blood Siphon's 10% oxygen regeneration per catch. Slower, harder-hitting weapons regenerate more oxygen per proc than fast, weak attacks.
Kraken's Weight bonus allows carrying more fish per trip, reducing return frequency. This synergizes with tubes that provide high oxygen capacity, enabling longer expeditions into deep biomes where rare fish spawn.
Anglerfish's Abyssal Light eliminates the need for external light sources in dark biomes. This frees up equipment slots for oxygen tanks or weight-boosting gear instead of lanterns.
