Hi, I've changed the trophy requirements with one of the latest patches, you now have to beat act 3 instead of act 4 in order to unlock them.

most of the time i lose before act 3 mainly due to how cards "luck" and combos not working with what i need

@Rage something that may help you, is understanding the autosave function, it saves after a battle has been concluded (you reach 0 hp or all enemies reach 0 hp), as for events; it's after you enter the next symbol on map and Not after you make choices.
This means you can quit and then go continue to try a fight with different series of draw cards/choices, of if you want to simply make a different choice in an event or shop.
This is especially useful for miss-clicks.

The Level above this is having the auto save folder open and tabbing over and copy pasting the save file, thus allowing you to now treat the game as if it had manual saving.
You're already reached modding stage of owning your game, so can consider this an optional manual save mod feature ;)

location: in your steam game install location:
\Steam\steamapps\common\SlayTheSpire\saves

yea i've have used that however even when using that you can still be dead reguardless of what your doing with the enemy.
