How to unlock the 1HKO (Hitless run) trophy

In this really short guide you will learn one simple trick to beat 1HKO. I did it in my first attempt, but I admit a bit of luck is involved.

The basics

The 1HKO game mode is relatively simple. You have to pay 1 gold coin (dropped from bosses) to enter, and then go through 24 floors (12 normal floors and 12 boss floors).

Unless you are a masochist, I suggest you take the strongest character you have (preferably Yuuka, Reimu, Alice, or other raw DPS characters). Levels don't matter because you will start at level 1, and you can't take any items in either, similar to Rogue Mode.

Skill Points

SKILL POINTS
The first thing you want to max out is dodge. It can and WILL save your life. After that, focus on whatever makes your character kill enemies faster. (For Alice it's Crits, ATK and ATK Speed; Yuuka only needs MATK and MaxMP, Reimu is something of a mixed bag).

Equipment and items

EQUIPMENT AND ITEMS
Here's the thing. This game has a hard cap on stats like dodge, meaning you can't get over 65% dodge chance. Some cards don't work either, like Orin's clothes since they only give you dodge based on the hearts you've LOST.

Don't stack dodge clothing cards like crazy. Pause the game and check the "Stats" page to see your total dodge, and it should tell you when to stop adding cards. Try to find a good mix between raw DPS and dodge.


However, there is a holy grail that can and will carry you, and this is where the luck part comes into play. Explore EVERY room in the early floors until you find Korindou or find the Holy Grail: Eirin's clothing card. It gives you a shield every 100 kills at EASY/GRAY rarity, and each piece you equip decreases the charge time.

How to save time between attempts

HOW TO SAVE TIME
I'm not trying to say you won't succeed, but be prepared for many, many fails if you don't have the Yuuka DLC. Yuuka essentially mops the floor with the enemies and bosses, trivializing every achievement in the game. There is a way to save time, however.

Once you are confident enough in your DPS and level, you can start to skip floors, going directly to the exit to challenge the next boss. To do that, you simply need to learn how to find the exit.

The exit will ALWAYS be exactly 2 rooms away from the spawn, which means you merely need to go 2 rooms in one direction, and if the second one isn't the exit, go back to the spawnpoint and try a different direction. This can also be used on endless mode to skip levels once you reach the level cap.

Kokoro and Minoriko are also good with OHKO since they have i-frame skills which as long as you find magic items you should be good. Oh also you don't really need to burn up your stock of gold coins since you can make a backup save then reload it
