Neoverse

Whilst this will likely come from progressing the other achievements, if you want this one in a hurry I would suggest the following:

Start New Journey
Select Claire with Priest loadout
Adventure Mode - leave Trancended Universe unticked
No other set up required, just start the run

I tested multiple times and there were only 3 different enemies I would face in the first battle:

Neon Rifle - attacks for 5 every 2 turns
Neon Red - attacks for 2, 4 and 5
Neon Blue - if you get this one, exit to title and start a new journey

I personally did this with Neon Rifle as you can just play "Compromise" (block 5) every turn you draw it and as long as you don't stack it twice, it's a guaranteed parry and just skip every other turn.

With Neon Red, you will need to use your "Shield" (block 2) cards but these have the "punishment" buff on them which means the enemy will die at some point but you can easily block each of these attacks with the perfect amount required and just exit to title afterwards and start a new journey.

A "Parry" is just like a "Precision". Only this time, this is where the enemy is attacking against your Armour (generated from the Blue Defend type cards). If it is reduced exactly to 0, a "Parry" will trigger, which will stun the monster that performed the attack that triggered the Parry, rendering them unable to act the next round. Parries are more difficult to perform than Precisions, as there are normally fewer defensive cards in your deck, which makes them less likely to be drawn, or to have one drawn that grants the wrong Armour value.

If you want to specifically go for this, rather than earning it just by playing the game for other achievements, try and bias your deck towards Blue cards as heavily as you can. The rest is simple arithmetic with the damage of the enemy attack, the Armour you may already have and how much each card grants, as well as how much Mana you have available.
