I think the No chest achievement is the hardest achievement in the game. Before playing this challenge, I never realized that buffs that can be found in chests are so important.



First of all, all power ups should be maxed and I suggest you try to unlock the achievement on the dungeon map.


As a pet, I don't have a recommendation. You can use dragon for early survival or use the robot to collect experience points easy.


I unlocked achievements choosing the archaeologist in my attempts. That's why I recommend to choose the archaeologist.

I think it will be a strategy that will surprise some of you.

You will unlock the achievement by playing in no skill game mode.

Reason: Making choices to strengthen the main attack, rather than splitting points among the options available to you when level up. Removing abilities gives us a chance to make choices that boost main stats more often.



At this point, a little information comes into play. Even if we play in the No Skill game mode, the Clones skill still appears in the selections. Take it when you see it.




Damage (minimum 2500),

Crit c. (around 20% is enough),

Crit d. (no limit),

Exp gain (get a few at the start of the game and if they appear after you run out of rerolls and you have no other logical choice)

Attack speed (must be at least 5)

First Passive Card Choice: I suggest you to choose the demon slayer emblem.



You definitely need to choose Tornado Fire as Active Skill. Because while it hits 2 times the attack power you have as damage, it reduces the damage you take. If you find a power-up for Tornado fire, don't miss it. You will need it to reduce the intensity of the last minutes.

Finally, the risky card can be decisive, and trying your luck can throw the run away or make it incredibly easy. (But I still recommend it because you will need to find an easy way to collect experience points around.)
