Welcome to another installment of our Princess Connect! Re: Dive story event guides! This event will be released with the character Tomo. For memory shards, you'll be able to obtain more Jun and Yukari shards. Today we'll break down the event and other pertinent information. All the information is from the JP server first ran the event, and if past events are anything to go by, we should be following the same reward chart. So let's head right into the article!

Tomo Banner

You're probably wondering whether it is worthwhile to roll for Tomo. First you'll notice she gets added to the standard banner and rotation so you should get her eventually. However, if you want a decent addition for clan battle and another frontline damage dealer, this is the best chance for you to roll her. Overall, she's a very good character and will be useful for at least the next 6 months or so.

Ironclad Nightmare Story Event

This is the sixth story event in the EN/WW server. Events generally give a generous amount of items, mana, jewels, and character memory shards. The memory shards featured in this event are Jun and Yukari. On top of the rewards, it also adds event story chapters which can be viewed as you complete the event stages.

Stages

Events are broken down into two phases of stages similar to the main quest. However, you must clear all the normal stages and the normal boss before unlocking the hard stages. Normal stages start at 1-1 and go all the way up to 1-15. Clearing each stage for the first time also provides 30 jewels, an assortment of items, and boss tickets. After the first clear, they will still provide some items and more importantly boss tickets. These boss tickets are used to fight the boss of the event. We'll go over this more in-depth later.

After clearing stages 1-1 through to 1-15 and the boss on normal, you'll unlock the hard missions. These missions are similar to the main quest hard missions and have a chance to drop memory shards. Each first clear will also provide 3 of the memory shards of the character indicated, boss tickets, items, and will also give the 30 jewel bonus. Each subsequent clear will then give a chance of dropping the memory shards. You can only clear each hard stage 3 times a day.

For the most part, you will want to clear each of these hard stages every day of the event to maximize your memory shard gain. This event features memory shards for Yukari and Jun. You definitely want to get as many Jun shards as you possibly can as there is only a single hard node in regular missions to farm her memory shards. There is a large amount of luck involved with the hard missions but the memory shards and the boss tickets are generally worth it.

Boss Battle

Luckily, the Very Hard boss is easier thsi time around assuming you have the right characters. (I hope you have Jun and Makoto) Completing it in one hit is entirely possible. You get quite a bit more rewards from it and you can only complete it once a day. Worry not, we'll have some more details on how to deal with this boss below.

To fight the boss you'll need to obtain enough boss tickets. Each of the stages you clear from the event will provide boss tickets. The boss will come in normal, hard, and very hard. The normal boss should be easily cleared with any team while hard may pose a bit more of a challenge. Very Hard, as previous stated will be a tough one. Clearing bosses will also provide tokens to be used on the event treasure box. This is the real reason you'll be farming the event. We'll touch on this later on in the article.

The hard and very hard boss will have a larger pool of HP and also additional skills. Of course, with the more difficult boss, the rewards will also be greater. This version of the boss also does more damage and has a more difficult attack pattern once below 40% HP. (Think of it as them hitting their limit break.) We will recommend some potential parties below for those struggling to clear the hard and very hard versions of the boss.

Difficulty HP Union Burst Skill 1 Skill 2
Normal
Lvl. 25
35,000 Large physical damage to all enemies based on the character's max HP and reduces physical defense and physical damage. Large physical damage to enemies in the front range. N/A
Hard
Lvl. 50
190,000 Large physical damage to all enemies based on the character's max HP and reduces physical defense and physical damage. Large physical damage to enemies in the front range. Reduce TP of 3 enemies with the highest percentage of remaining HP and self physical damage up.
Very Hard
Lvl. 90
1,100,000 Large physical damage to all enemies based on the character's max HP and reduces physical defense and physical damage. Large physical damage to enemies in the front range. Reduce TP of 3 enemies with the highest percentage of remaining HP and self physical damage up.

So as you can see above, Very Hard can still pose a challenge. With over 1 million HP, this thing can soak up quite a bit of damage. Just note the boss does deal AOE damage and reduces TP as well. You'll want to manage your team's HP pool well so your units don't end up dying to the second skill and UB. Also don't forget about the 40% enrage mechanic for the Hard and Very Hard boss. Defeating the Very Hard boss will also drop a large amount of rewards and a Jun memory piece. Remember, you can only defeat the Very Hard boss once daily.

Suggested Teams

Hard Boss

For the hard boss, it should be pretty straightforward as the enemies haven't been upgraded too much compared to our level cap and rank increases. This worked in JP assuming your characters are rank 9 and above and around level 90 or so. You may need to level up your characters or try different combinations to get a decent clear. The boss move set for Hard and Very Hard are the same but the health and damage is much lower. Be aware of all the AOE damage between the UB that does damage to all your units and the skill 2 that hits your three units with the highest % of remaining HP left while reducing their TP. We'll suggest a few parties below: the approaches can vary but all of these should work.

Yui Shiori Kokkoro Kaori Miyako

Our first party consists of a tank and Kaori up front with a Kokkoro for support and Shiori + Yui in the back. Most of the characters here are interchangeable and your results may vary. This is probably the easiest team to build just because the characters are easily obtainable. You can easily replace Miyako with another tank such as Jun. The DPS slots can also vary between using a different archer such as Arisa or Suzuna. If you don't need the healer, feel free to replace Yui with another damage dealer.

Very Hard Boss

Moving on to the Very Hard boss, you'll need to be aware of your team's HP bars. Having your units at too high HP can be dangerous as the skill 2 will hit them and reduce their TP which would likely bring down your DPS. Just be careful for both the AOE damage and the skill 2. As long as your frontline survives and you have some semblance of damage, you'll be fine.

Saren Makoto Kaori Jun Miyako

The above team can potentially one cycle clear the very hard boss. You'll need mostly max stars and rank 9-6 for your damage dealers to achieve it. This is probably the easiest team to use but also requires you to have Jun and Makoto to function properly. An alternative to the above composition which is a safe 2 cycle clear is replacing Saren with Tamaki and replacing Miyako with Nozomi.

Yukari Tamaki
(Summer)
Makoto Kaori Jun

This second team composition can also potentially one cycle clear the boss. If you use Yukari, you'll need to manually run this party. You can replace Yukari with Shizuru or Akino for an auto team. You can also consider running Kokoro (Summer) in Yukari's place. With enough stars, levels, and ranks, your units should survive enough to one hit the boss. Otherwise, you can always do this over two or three hits. Your first clear of the Very Hard boss will get you 10 Jun memory shards so it's absolutely worth doing, but if it takes you more than three hits to kill, considering just killing the Hard boss for subsequent attempts.

Rewards

We're finally onto the main point of each of these events. The rewards that come along with it. In addition to the first clear bonuses, there are also a set number of event treasure boxes. Think of it as a mini gacha machine but each one has a set number of items. To roll this treasure gacha box, you get pulls from defeating the event boss and completing daily missions. You do not need to clear out every single item in each box to move on to the next one. However, you will need to obtain the main items in the box. In this case, the main items are the memory shards for the characters. (You would want to collect these anyway.) The contents of each of the boxes are listed below.

Total Memory Shards

A breakdown of all the possible memory shards gained from missions, story, and the boxes are listed here:

Location Yukari Jun
Story Reward 4 4
Normal Quests 2 2
Hard Quests 6 9
Treasure Box 50 65
Event Missions N/A 20
Total 62 100

Note: This does not include memory shards from hard mission drops. These only include the ones you are guaranteed to get assuming you complete the tasks.

As you can see, you'll be getting a lot of memory shards for Jun. The first clear of the Very Hard version of the boss has a mission that gives 10 Jun memory shards so be sure to at least clear it once if possible.
