Mortal Shell: Enhanced Edition

As of 2021-01-21, you will earn this achievement despite having the following items missing from your Compedium;

- Rotten Gourd = listed underneath Rotten Food in Consumables, normally dropped from rare-spawn Halloween seasonal enemies.

- Foul Censer = listed underneath Perfumed Censer in Key Items, location listed below.

- Glimpse of Reverie = listed underneath Glimpse of Oblivion in Experience, obtained by killing the Tutorial boss or by killing the weapon bosses whilst in NG+

- Glimpse of Cowardice = listed underneath Thestus' Glimpse of Tenacity in Experience, location listed below.


There may be other non-required items, but these were the ones I was missing after following the excellent walkthrough from BaggaOne on TA, and yet I still earned the achievement.


You can obtain all required amounts of all items in one playthrough except for the Baguette, which you can get easily at the start of NG+ by heading straight to the necessary chest.

Below is a complete list of all non-seasonal items in order of their listing in the Compendium, along with the amount of times you need to use the item in order to Master it in (brackets). Originally obtained these descriptions from the link below. Copy/Pasted here in case the website disappears.
