Anime Legacy Simulator Fourth World: How to Unlock It and What to Do Inside

To unlock the fourth world in Anime Legacy Simulator, finish the quest line on the third (JJK) map: open the main quest icon, complete the JJK stage quests by clearing the monsters there, and the new world unlocks. Once you're inside, the Seven Deadly Sins-themed map hands you four objective chains to pursue — the Commandment system, Ban's secret quest, Lion Token collection and the artifact system — plus an hourly world boss and a map boss that drops a head accessory granting a 50% player damage buff (and can also drop an artifact).

How to unlock the fourth world

The fourth world sits after the JJK-themed third map and was added in Update 1. It's based on The Seven Deadly Sins, and since no source gives it a distinct in-game name, guides simply call it map 4.

Opening it takes three steps:

1. Get to the third map. The unlock assumes you've already progressed to the JJK map.
2. Open the main quest icon and work through the JJK stage quests.
3. Clear the monsters on the JJK map. Once those quests are done, the fourth world unlocks and you can warp in.

If you started playing during or after update 1.5, you'll meet this gate as a map 3 defeat quest that was added specifically so players can move on to map 4 — finish it and the new world opens.

Still climbing through the earlier maps? The Anime Legacy Simulator beginner guide and progression guide cover the road up to the JJK map, and the worlds overview shows where map 4 sits in the bigger picture.

Objectives to pursue inside the fourth world

Earn Commandments from the hourly world boss

A world boss spawns in the fourth world every hour and stays for 15 minutes. Its 5,000 HP ignores your characters' damage — the boss goes down by click count instead, at roughly 1 damage per normal hit (2-3 for high attack-speed units, about 10 DPS in total). Fighting it solo takes a while, so the practical play is to pile in when the whole server attacks; that's what makes the fight fast.

The boss drops divine items at the percentages listed on its in-game drop list, plus the Fairy Wing back accessory, which also grants some Fighter damage — though one player who farmed it reports the wing's drop rate is quite low.

Defeating world bosses is also how you earn the marks tracked by the Commandment NPC. The Commandment items themselves — 10 types, each with a different buff and its own individual tasks — were reported at about a 5% drop rate, and each maxes out at level 10. Since update 1.5, surplus task progress carries over when you manually upgrade to the next task, but the system still doesn't auto-upgrade. The Commandment guide breaks the system down, and the world boss guide covers spawns elsewhere in the game.

Take Ban's secret quest for the Gideon weapon and plushie mount

Ban hides behind the spawn point:

1. After warping in, turn around toward the coastal beach behind the spawn.
2. Walk to the back corner of the beach — the written guide pins it as the back-left corner.
3. Talk to Ban to accept the quest. Mind your step: that corner has glitched invisible walls.

Accepting the quest previews the weapon reward, a costume-style item with strong base stats and very powerful skills that attacks slowly. The quest target waits at the far end of the map: head to the very end near the end boss, turn right at the end-boss arena, and step into the big hollow rock formation there — the secret boss is inside. Fight it to complete the chain and collect the weapon's pieces. Per the wiki's secret-boss guide, the fourth world's hidden boss is Chaos Arthur with 1,500,000,000,000 (1.5 trillion) HP — the game's most durable secret boss as of Update 1.

Completing Ban's objective brings two rewards:

• The Gideon weapon — strong base stats and very powerful skills, at the cost of slow attacks. More on the slot in the weapons guide.
• This world's exclusive mount, a pillow plush that a later recap identifies as King's plushie and calls the game's best mount, faster than the Jujutsu wolf (65 vs 60 as stated there). Comparisons live in the mounts guide.

The secret boss also drops loot directly:

Routes for every world's hidden quest are in the secret quests guide.

Farm the regular map boss for the damage accessory

The fourth world's regular map boss — the zone boss at the end of the map — drops a head accessory that replaces Gozu's blindfold and gives a 50% player damage buff. The secret boss drops the same accessory, but the regular boss is the easier farm, and it can also drop an artifact. For that slot, see the accessories guide.

Collect Lion Tokens for the Lion Progress NPC

Lion Tokens drop from the monsters scattered around the fourth world's map and from a boss the update tour calls Gokumon. They feed the feature at the Lion Progress NPC, described as the 'Fighter Age', which the tour calls quite useful — so sweep the map's mobs as you go and you'll bank tokens along the way.

Learn the artifact system at the Scanner NPC

The Scanner NPC explains the artifact system. Each artifact drops differently — for example, the clock artifact comes from the Easy Dungeon loot box — and the blue text at the Scanner shows where every artifact drops, so check it there before grinding for a specific piece. The dungeon route itself is covered in the dungeons guide.

Units and extras that shipped with the world

The same update that added this world also added a summon banner with its characters — 40M per pull at launch — including the secret unit Meliodas (244 base damage, about 366 shiny), described as very hard to obtain. Read the summoning guide before spending, and weigh options against the best fighters list. Don't skip the Index rewards section either — it lets you claim extra items.

Bottom line: finishing the JJK stage quests is what opens map 4, and once you're inside, Commandments, Ban's secret quest, Lion Tokens and artifacts give you long-term goals to work through.
