A set of saves contains a complete walkthrough from the beginning of the game to the first floor of the tower of the final moments of the game (the last possible save).
For specific achievements, the in-game time will be given for orientation among the many save files:

• 00.28.26 or 00.21.54 - kill the goose
  
• 00.54.34 - kill the bear beetle
  
• 05.59.36 - spend 20k in church + participate in talent show
  
• 06.15.31 - drink in every tavern (or you can load the next save and try to drink in the bar again (I already drank)). Also at this point you can buy from the map trow
  
• 10.00.55 - 20 amulets. Go to the left side of the map and listen to the story (kindly) or escort the quest character. You can also load the next save and just talk to him, it will be the 21st amulets, maybe trigger the achievement. Also (if only the first mage summoning is counted) no summoning stones have been used here yet.
  
• 10.51.15 - go through the game in old school mode. I chose finaoch, since I read that kaleih is difficult. THE CHOICE TO LEAVE WILL ONLY GIVE OUT FOR PREVIOUS DIFFICULTIES. The tower is easy, the boss too. Use summons - there are a lot of stones.

For all other achievements (if you suddenly did not get them for some reason), use other guides to understand where and what is located. For 5 and 10 amulets, open the inventory and watch when they become 5 and 10. Check the chapter log. Check the already picked up summons.
