Dimension Border is a series of instanced dungeons for fighting powerful bosses. You will need to move through several areas of the dungeon, fighting several groups of smaller monsters, before encountering the big boss itself.

Each Border has multiple levels of difficulty, unlocked when you reach a certain class level. The bosses can drop strong accessories or skill books, as well as tetroblock pieces, with better rewards at higher difficulties.

Every week, one of the standard dungeons will have a special dungeon event, providing more challenge but more rewards. There will also be a challenge dungeon on the weekends, which is a replay of the solo challenge modes from story episodes. Ranking highly in this mode provides you with a variety of rewards.

You can get more information on the current week's schedule, which lists which normal dungeon is having an event, as well as the gimmick added to that dungeon. You can also see what the weekend challenge boss will be.

Entering a dungeon

You earn one dimensional boundary ticket free each day, for a maximum of 7. Additional tickets can be purchased in the shop with diamonds or paid currency. Entering a Dimensional Boundary dungeon costs 1 ticket.

You can chose to spend multiple tickets, up to 5, on a single entry, as long as you have enough in your inventory. This will not change anything in the dungeon itself, but you will get rewards based on the number of tickets used. This allows you to both save up tickets and use them in bulk, which reduces the number of times you need to challenge Dimension Border weekly if you still want to use your tickets efficiently.

When entering a dungeon, you can let the system match you with other players, or you can create/join a party and enter the dungeon with that group. Entering with a party is how you can reliably clear the battle pass challenges (such as clearing the dungeon witih 3 or less party members or clearing it solo.) You can also enter the dungeon solo and send up backup requests while you are in it.

Battle Passes

Each standard boss has a battle pass system for its dungeon. There is a normal pass and a premium pass, which is purchased with diamonds. At first the pass goes up to level 50, but you can unlock 50 additional levels by spending diamonds. If you've already purchased the premium pass, it will be expanded with the unlock and you do not need to purchase it again.

To increase the pass's level, you must clear a variety of tasks. These include clearing the dungeon a certain number of times, within a certain time limit, with a limited party size, etc.

Token shop

Each standard boss has a token shop where you can exchange various boss soul drops for tetroblock pages, pieces, and skill books. Extra tetroblock pages are recommended for immediate purchase, with skill books coming after. You should get enough tetroblock pieces from fighting the dungeon that the packs would not be useful, but the peapod familiars and mount decoration boxes may be useful if you're trying to level something up quickly.

Standard dungeons

There are 3 standard dungeons, although each week they cycle through which one is designated a Special Dungeon.

The first 4 levels are standard difficulty and provide normal boss soulcores and a rare elemental attack skill book drop. The 5th and 6th levels are hard difficulty and provide true boss soulcores and a rare elemental passive skill book drop.

Natrum's Nest

Natrum's Nest is a wood-element dungeon that replicates an early main story quest event, where you need to rescue Natrum from the Chaos Gates' influence. In the Dimensional Boundary, you must travel through several zones to make it to the main lair, where you battle Natrum, a giant dragon.

Frozen Laboratory

The Frozen Laboratory is a water-element dungeon from the Glittering Grotto. You must navigate the dungeon to figure out what the Black Wheel is plotting. At the end of the dungeon, you will face off against Proto Mark 13, a mechanical contraption.

Fiery Mt. Know-how

Fiery Mt. Know-how is a fire-element dungeon. You need to travel through several zones to stop Envy of the Black Wheel from destroying the volcano. At several points there will be a barrier; you will need to wait here momentarily until a plot trigger allows you to damage and destroy the barrier to continue. At the heart of the volcano, you will fight Volcanord, a 3-headed snake.

Special dungeons

The special version of each dungeon has several changes from the standard dungeon. A new difficulty level, "Heroic" becomes available. The special version of each dungeon introduces additional gimmicks alongside the standard dungeon mechanics -- see the dungeon's entry page for specific details.

Each week, the first 15 times you enter the special version you can get additional high-level rewards (like little genies); using multiple tickets at once will decrease this number accordingly. Once you've cleared this number, you will only get standard drops.

Special dungeons gimmicks

These are gimmicks that have appeared previously in Dimension Border.

Dark Pillars

Multiple dark pillars will appear in each zone and spawn spider monsters that can quickly swarm party members. Destroying the pillars will stop more spider monsters from spawning in. This is important to do in order to prevent the party from being overwhelmed.

Cannons

A trio of cannons will appear in the opening zone of the dungeon. All monsters in this dungeon have a strong shield protecting them. While you can destroy the shield with normal attacks, using the cannons is much faster. You will need to carry the cannons with you to each area of the map. Once the shields are destroyed, the cannons are not useful and can be ignored.

Poison zones

Poison zones will appear around characters. If a player is poisoned by it, they will spread the zone to another area and possibly catch additional players in it.

Flame zones

Flame zones appear around monsters when they are at low health, requiring you to dodge around them or take considerable damage and possibly get knocked back.

Petrifying monsters

Flora monsters will spawn and attack players. If they can hit players they will increase their stone curse meter; if it reaches 5, that player is turned to stone and cannot act unless the curse is broken. After about 5 seconds the curse will kill the player.

Frog curse

Every so often, players will be turned into frogs and cannot attack, use skills, or dodge roll. Although the curse wears off on its own, this takes a long time. You can manually remove the curse by ribbitting (typing ゲロゲロ in area chat).

Enraged boss

Every time the boss lands a hit from a telegraphed attack on any player, its rage meter will go up, increasing its attack.

Challenge Dungeon (Time Attack mode)

On the weekends, a challenge dungeon will be available. These cycle between different repeats of story episode solo challenge dungeons, and function in a similar way. The boss uses the same attack patterns as it used in that story episode. Your challenge is to do as much damage to it as possible within a time limit. Depleting the boss's health bar will cause it to shift to the next level, where it regenerates with higher stats; this also increases the time limit by a small amount. The challenge ends when you either run out of time or HP.

Your total damage is compared across the server to determine your ranking. Rankings are separated by class, which allows you to compare yourself with others on your server.

At the end of the weekend, rankings are finalized and rewards are given to players who rank 150 or higher.
