-Super Supporter - After you rescue 18 to 21 or so villagers you will be able to upgrade one of the support runes you bought for the helping hands achievement,to Level 2 and then Level 3 and the achievement should unlock afterwards.

Let Me In ! - After you rescue 30 villagers ,you can buy the last key rune which will take you to the final boss but don't fight the final boss just yet, since the final boss is the last thing you should

Avid Reader - The following achievement ties into this one, you have a chance to get a dungeon section with journal entries and you can also get them from boss fights at the end of each dungeon. This is IMPORTANT, you can only get 34 Journal Entries and the last two are at the final boss so you are expected to get this achievement last if you follow the guide

• Apprentice ,Veteran,Master and All Aboard - Boss dungeon does not count and has no villagers to rescue. So complete all 15 dungeons and rescue 3 villagers per dungeon. You can do this in a single run. Just remember this, Floor 2 and 4 each have a villager and the heart of the dungeon aka floor 5 has a villager and a journal page after you defeat the boss of that dungeon.

So after you have gotten every achievement expect Avid Reader you can do the final boss dungeon. And before you enter the last boss dungeon make sure you have 34 journal entries, if you are missing journal entries simply replay previous dungeons until it says on Steam progress bar for Avid Reader achievement you have 34 journal entries. Then go do the final boss dungeon and defeat the final boss. The final boss has two unique journal entries that are not anywhere else in the game. So after you have defeated the final boss and picked up the last journal page, the 100% should be yours.

Expected time to 100% completion is 8 to 11 hours depending on RNG and how good you are at FPS games.
