The Adventures of Elena Temple: Definitive Edition (EP)

This achievement is for completing all rooms in the Chalice of the Gods dungeon. To clear a room, you must collect all coins and gems and shoot all pots in the room. There are 49 rooms (7x7 map).

I'm not sure if the three scrolls are required, but they're easy to obtain as you go through all of the rooms. Also, the Scroll of Completion will help you significantly since it will show a check mark in each room you've completed.

Assuming you pick up the Scroll of Completion, this is how your map should look when you're done. The achievement will pop right away after you clear the last room.
