Coliseum annoucement

Example of the new challengers update

General Info[]

Schedule[]

The Coliseum is an arena introduced in OPTC 5.0 (in September'16) where you can fight and obtain characters that do not appear anywhere else in the game. Ideally, you will want to clear all smaller battles and then farm the boss posters and other rewards on the toughest, 20 to 50 stamina "Chaos" difficulty (it has ~6,300 EXP but is usually pretty tough). Now, on to details.

Coliseum appears on Extra Island. Every new character stays for 3 weeks, which means you can encounter them over 9 days (these days, usually for a full month, give or take, through not necessarily every day - every second or so). They go through some sort of rotation and reappear every few months when new Colosseum batches are released, similar to Fortnight release schedule. Each coliseum will feature between two to five different farmable characters.

Originally Coliseum was available only on Wednesdays, Saturdays and Sundays. Since October 2017 Coliseum frequency increased, with the 'return' (or 'repeat') Coliseum featuring only some old units added. The 'return' Coliseum appears on Tuesdays and Fridays and is on a 2-week rotation and never features new units, only ones that appeared in past Coluseums. Since June 2018 the 'repeat/return' Coliseum now features the new Coliseum boss too, so it is not really a 'repeat/return' anymore, and the coliseum schedule got rather confusing. As of 8.4.0 in Fe'19 coliseum was extended to all days of the week.

2018 also introduced Neo Coliseum s described on a separate page.


Loot[]

Loot in Coliseum includes turtles, cotton candy, cola, forbidden tomes (aka socket books), boss posters and manuals for the boss characters. Non-boss characters, including mini-bosses, which the game can pull from anywhere, WILL NEVER DROP A POSTER. The only poster that can drop is for the final character on the final stage. As usual, the drop rate increases with difficulty. Any final stage boss has a drop chance (yes, that means you can get posters on final Exhibition and Underground stages), but only Chaos has a 100% drop rate. Clearing each battle for the first time will generate some extra rewards, from rainbow gems to other loot. Like fortnights, these completion rewards wont be earned again even if the Coliseum reappears in the future. What kind of rewards is pretty much set and similar for all difficulties, and as for the loot, of course with higher difficulties giving better loot (50 stamina Chaos coliseums have a very high, maybe over 50%, drop rate for forbidden tomes, for example).

As usual, quality of characters you can recruit varies. Some characters can appear only on some difficulties, and as usual, the ones exclusive to the hardest (chaos) level are probably the most useful. Some of the non-chaos characters like Mr. 7 and Ms. Father’s Day are pretty useless while others like Coby, Hero of the Battlefield Navy Petty Officer are totally solid. Similarly, among Chaos level characters there are ones which are very useful (a lot) and a few which are not very appealing (ex. Diamond Jozu Whitebeard's Third Division Commander ).

Difficulty and battle structure[]

Coliseum has 3 different tournaments for every wave, with 3 difficulty levels:

  • Exhibition (3 easy battles, 2x10 stamina and the 15 stamina boss battle). 
  • Underground (4 medium battles, 3x15 stamina and the 20 stamina boss battle)
  • Chaos (5 hard battles, 4x20 stamina, and the 30 stamina boss battle. The difficulty here, particularly of the final battle, can be compared to 40-60 stamina Raid/Clash). Rewards: 1 Forbidden Tome, 1 Amber Hime, 5x Cotton Candy, 3 x Gems , 5x Forbidden Tomes. Since the 18th Wave, some Chaos coliseums have a different stamina distribution - 4x10 or 4x20 stamina, and the final one is 50 stamina. 

Like most features in Extra Island, the recomended level for going in is shown in the Tips section, even if the crew you have is usally far more decisive than the level.

The opening battles of each arena must be cleared in order. Every battle is always 5 rounds long, no exceptions. Once you clear an opening battle, the next one is unlocked permanently. So even if you can't clear a battle before the Coliseum ends you can retry from where you left or farm in a cleared stage. You will face the droppable boss in the last round of the last battle. Depending of the boss, he may come or summon units to aid him.

In Chaos difficulty, the final boss battle always feature the enemy from the 4th opening battle on the 4th round. Chaos boss battles usually work like this: you get 3 rounds of grunts, boosters and evolvers (one of which always has a turtle that hits for ~2.2k in case you need to stall), then the enemy from the 4th opening battle, then the actual boss. The enemy on the 4th round generally has considerably less HP than what they had when you fought them on their opening battle, and sometimes they hit for slightly less damage; specifics vary from sub-boss to sub-boss. They will bring any grunts they had in their boss battle. This pattern is different in a 50 stamina Coliseum, where the 3rd battle will also feature a boss, this one randomly chosen from stages 1-3, again with less HP and grunts if any previously. The 4th stage for 50 stamina is the usual 4th battle boss. This may become more diverse in the future, for example the 50 stamina Shiryu coliseum featured a miniboss (Doc Q) and the final boss (Shiryu) together on the 5th stage.Newer Arenas, like Lucy's, may feature mini-bosses even in the lower difficulties.

All Coliseums can feature a rare secret stage with Heracles. He has very high defense, ~50HP, CD=2 and ATK of ~5500. He is guaranteed to drop a Forbidden Tome.

Some Coliseums can be followed by an Ambush (this is noted in the description of limited time events).

History[]

Coliseum schedule is no longer updated since summer 2018, it got too confusing, and nobody ever said this list was useful. (Feel free to take it over; list of raid bosses by chronological appearance can be also found in the German community guide).

How to beat Coliseum X[]

See specific pages (and see comments on those pages to links to other guides specific to those colos, like reddit guides):

Those are posted in the order they were released. Newest ones are on the bottom.

(This list is not mainted much as there is nobody interested in creating detailed coliseum analysis - you can take this role over, it's a wiki!)
