This guide will show you the step-by-step process on how to unlock the Koishi boss fight in Touhou Blooming Chaos 2!

Invoering

Here’s a simple guide on how to have a boss battle with Koishi in Touhou Blooming Chaos 2. It’s important to note that you do NOT NEED DLC 2 to engage in a battle with Koishi in this game. You can start the boss fight against Koishi as soon as you discover her special room. DLC 2 only gives you the option to play as Koishi as a character.

How to Find Koishi?

To locate Koishi, let’s start by finding her room! Koishi’s room is a unique space that might appear randomly as you explore dungeons. The likelihood of a special room appearing can vary between different dungeons, and there’s no guarantee that it will be Koishi’s boss room.

If you wish to boost the chances of encountering a special room, you can equip the “Ordinary Rabbit’s Skirt” (Tewi’s Dress Card). Each card increases the special room spawn rate by 1 naar 3%, and these effects can stack. Bijvoorbeeld, het uitrusten 6 Phantasm “Ordinary Rabbit’s Skirt” cards will raise the special room spawn rate by approximately 18%.

Koishi’s Special Room

Nu, let’s talk about Koishi’s special room. After completing multiple dungeon runs and increasing your special room spawn rate, you will eventually come across a special room that stands out. In this room, you’ll find a purple telephone situated in the center, and when you enter, the music will stop, creating a unique atmosphere with no background sounds.

Op dit punt, you can start the process of unlocking Koishi’s boss battle by simply approaching the telephone and selecting the “Dial any number” option to initiate a conversation with Koishi.

What Koishi Wants

After you have a chat with her, A “quest line” for Koishi begins, and she’ll ask you to bring her a total of 10 consumable items before you can challenge her in a boss fight.

Koishi’s requests will be for random consumable items, which you can see displayed above the telephone in her room.

When you have the requested item, simply toss or drop it on the ground, and the telephone will “absorb” Het. Make sure to throw the item in front of the telephone so Koishi can collect it.

After a few moments, when the item is “absorbed,” you’ll need to talk to Koishi again to proceed. She’ll express her gratitude and reward you with a “Forbidden Number.” We’ll delve into the significance of these “Forbidden Numbers” shortly.

On the next interaction after receiving the “Forbidden Number,” Koishi will thank you again and remark that it’s a good day.

This process is repeated 9 Meer keer, in totaal 10 deliveries. The 11th encounter with her will lead to the boss fight if you dial her on the telephone. It’s important to note that you won’t immediately battle her after delivering the 10th item.

Here are some key points to remember about Koishi’s “quest line”:

1. After delivering the item she requested, she won’t ask for another item on the same floor. In plaats van, you’ll need to encounter her on a different floor for her to request another item, which you can deliver right away if you have it.
2. If you lack the item Koishi asks for and you leave the floor without delivering it, she will request the same item in the next encounter. This allows you to retrieve one from your storage (if you have it there) or purchase one from Kourindou in the human village before venturing into another dungeon.
3. Koishi’s special room will only appear if the dungeon can spawn a special room. Bijvoorbeeld, dungeons like Boss Rush, where every floor features a story-line boss, won’t spawn Koishi’s special room, even though she technically qualifies as a boss.

Once you’ve completed her 10-item request, starting from the 11th encounter and onwards, you can initiate Koishi’s boss fight once per floor by dialing her using the telephone in the middle of her room. Koishi is quite an aggressive boss, unleashing numerous area-of-effect attacks and possessing invincibility that renders her impervious to damage.

• It’s advisable to come prepared with a plentiful supply of healing potions, Shanghai Dolls, and even MP potions for your abilities. Koishi doesn’t have a vast amount of health, but she gains invulnerability if you hit her too frequently or deal excessive damage in rapid succession. You’ll notice this when she’s encased in a clear bubble. Gedurende deze tijd, it’s best to evade her attacks until the invulnerability wears off.
• Koishi employs a specific attack where she attempts to strike you from behind your character. Om dit te voorkomen, dash when the red dot becomes barely visible, which instantly moves Koishi away from you and prevents damage. Echter, if you miss this window, you’ll be unable to attack or move and will suffer substantial damage. Ensure you have plenty of healing items on hand to avoid defeat.
• Upon defeating Koishi, there’s a chance she’ll drop her dress card. This card’s effect causes your character to emit an aura dealing damage to nearby opponents each time you dash, similar to Koishi’s own dash during the boss battle.

Whenever you provide Koishi with an item, she reciprocates with what are known as “Forbidden Numbers.” These numbers grant you the ability to converse with various other Touhou characters. You can keep track of the numbers you’ve gathered by using the telephone and selecting “Dial a number in the contact list.”

The conversations with these characters can be initiated an unlimited number of times and mainly serve as a source of experience. It’s worth noting that speaking to these characters isn’t a requirement to challenge Koishi; you can face her without engaging in these additional conversations.
