To clear World 1 in the Roblox simulator +1 Assassin Leveling (developed by the group +1 on top), players must defeat enemies across all 18 progressive stages. Defeating the Stage 18 boss immediately grants access to World 2. Reaching this milestone requires cycling between clicking or zone training to build Strength, fighting through stages to earn Wins (also referred to as Trophies), rebirthing to access higher-multiplier training areas, and purchasing sequential dagger upgrades.
World 1 Stage Progression and Recommended Strength
Combat in World 1 is organized into 18 distinct stages. Each stage tests your Strength pool against waves of enemies and intermittent bosses. If your Strength is lower than the recommended threshold, your health depletes rapidly, though landing special attack abilities deals burst damage that can push you past close battles.
Based on player playthroughs in World 1, here are the documented milestones and recommended Strength thresholds:
| Stage | Documented Enemies / Bosses | Observed Strength Requirement | Notable Rewards / Drops |
|---|---|---|---|
| Stage 1 | Goblins | Base level (1–50 Strength) | Initial Wins, tutorial items |
| Stage 3 | Wave mobs | 500+ Strength | 25+ Wins |
| Stage 5 | Wave mobs / Mini-boss | 1.5 Million Strength | Health shields, trophy gear |
| Stage 6 | Mid-tier mobs | 10 Million Strength | Increased Trophy drops |
| Stage 12 | Armored waves | 3 Billion Strength | Higher-tier Wins (2.5k–5k) |
| Stage 13 | Heavy mobs | 15 Billion to 75 Billion Strength | 10k Wins |
| Stage 14 | Elite waves | 100 Billion to 250 Billion Strength | 25k–50k Wins |
| Stage 16 | Late waves | 400 Billion+ Strength | High-tier item drops |
| Stage 18 | World 1 Final Boss | Recommended up to 1 Trillion to 5 Trillion Strength | World 2 Portal Access |
In player testing, attempting Stage 18 with under 1 Trillion Strength often leads to defeat against the boss's massive health pool unless your weapon's special attacks and stat multipliers are pushed to their limit.
Training Zones and Rebirth Multipliers
Rebirthing resets your current player level but provides permanent stat multipliers and grants access to upgraded training zones, such as specialized treadmills. Higher rebirth tiers drastically shorten the time required to reach billions and trillions of Strength.
- Early Rebirths (1 to 4): These early ranks raise your base Strength per click from single digits into the thousands. They enable you to clear Stages 1 through 4 with minimal downtime.
- Rebirth 5: Unlocks the 5x Strength training treadmill. At this level, slashes provide around 40,000 Strength per swing, making the 1.5 Million threshold for Stage 5 achievable in minutes.
- Rebirth 9 to 11: Unlocks the 8x to 11x training areas, pushing stat generation into the millions per slash.
- Rebirth 14: Grants access to the 11x–14x training area, generating roughly 3 Million Strength per slash. This allows you to bridge the gap into the tens of billions needed for Stage 12 and Stage 13.
- High Rebirths (16 to 27+): Players pushing into Stage 16 through Stage 18 rely on 20+ rebirths. With multipliers scaling above 2,000x and base training generating tens of millions per second, your Strength can rapidly climb past 200 Billion toward the 1 Trillion mark.
Weapon and Dagger Upgrades
Weapons must be purchased sequentially using Wins earned from completing stages. You cannot skip tiers, so farming earlier bosses for repeatable Win payouts is mandatory before taking on late-game stages.
- Basic Dual Swords: Default starting weapons granting basic +1 Strength per click.
- Royal Standard / Royal Blades: Unlocked early on (around 100 to 200 Wins). These blades provide your first noticeable flat bonus per second.
- Infernal Eye / Soul Eater: Mid-tier blades that provide thousands of flat Strength per swing and unlock unique special attack animations.
- Thunder Strike / Thunder Storm Sword: Costs 50,000 Wins. Provides +8,000 base Strength per hit (scaled further by your rebirth multipliers and pet buffs).
- Amethyst Sword / Shard: Requires 1,000,000 Wins. This weapon offers substantial power scaling designed to bridge the gap between late World 1 stages and the final boss.
- Higher Tier Weapons: A subsequent sword priced at 5,000,000 Wins exists for players preparing for World 2 content.
Auras, Pets, and Gear Modifiers
Strength from training is only one half of the progression formula. Multipliers from passive equipment, pets, and auras determine whether you can survive the damage checks in Stages 12 through 18.
Aura Unlocks
Auras are purchased directly with Wins and provide cosmetic effects alongside stat boosts:
- Blue Aura: Costs 25 Wins.
- Golden Aura: Costs 2,500 Wins.
- Angelic Aura: Costs 500,000 Wins.
- Spirit Flame Aura: Displayed at an end-game tier of 80 Billion Wins.
- Crimson Aura: Locked behind a 5-day login requirement.
Egg Hatching and Pet Multipliers
Eggs are acquired from quest rewards, milestones, or bought with Wins in the hub area:
- Normal Eggs: Produce common to rare pets such as Frogs and Penguins, providing minor flat multipliers.
- Rare and Chaos Eggs: Drop high-multiplier pets, such as an Evil Unicorn (4x multiplier), a rare pet (7x multiplier), an Epic Dragon, or a Phoenix (8x multiplier).
- Pet slots can be expanded through game passes (+1 or +2 equip slots), but free-to-play players should prioritize equipping their highest percentage multiplier pets at all times.
Item Drops and Gear
Defeating stage bosses yields equipment drops, such as Luck Pots, Rice Balls, Poison Jars, and Shields:
- Trophies / Wins Boosts: Items granting +3% to +6% extra Trophies should be equipped when farming stages you can easily defeat.
- Health Boosts: Items granting +5% to +15% Health are essential when attempting damage-check bosses on Stages 11, 14, and 18.
- Critical Damage: Secondary items roll critical damage bonuses (such as +8% or +10%), which synergize with weapon special attacks.
Best Strategies for Clearing Stage 18
- Stack Friend Boosts: The official game rules state that playing in a server with friends grants +10% Strength per friend. Grouping up significantly reduces AFK training time.
- Time Your Special Attacks: High-tier daggers feature dedicated special attack skills. When facing the boss waves on Stages 5, 11, and 18, trigger your special attack immediately as the boss closes in to take off a massive percentage of its health before it can deplete yours.
- Farm Stage 14 for Wins: Once you can clear Stage 14 reliably, farm it repeatedly to generate 25,000 to 50,000 Wins per run. Use these runs to purchase the 50,000 Win Thunder Sword and save toward the 1,000,000 Win Amethyst Sword before challenging Stage 18.
- Do Not Neglect Rebirths: If you hit a wall around Stage 13 or 14, do not grind clicks manually. Perform another rebirth to unlock the next treadmill tier. The multiplied stat generation from higher-tier training zones will return you to your previous Strength level in a fraction of the time.
