Sigil's are found in various locations of the Dungeon as well as in the Mind Dungeons.
The Dungeon Sigils allows one to quick jump to that Sigil.
There's currently four Sigils in the Dungeon:
- On the first floor, near the top. You cannot miss it as it's part of the storyline.
- On the fourth floor, from where you start, go around and head straight down. It's in the middle of the intersection.
- On the seventh floor, head into the upper right room. It's in the lower right corner.
- On the twelth floor, head straight left to the small hallway right next to you. Check the bottom 'room' for it.
- On the fifteenth floor, go into the small 3x3 room near where you start. It's at the top.
The Mind Dungeon Sigils allows the Protagonist to go to the next room, but not go back the way they came.
Trivia
- If you ignore a Sigil but unlock the next one (for example, ignore the floor 4 Sigil but grab the floor 7 one), all missed Sigils will be activated. Whether this is intentional or not is unknown.
