2 Wilderness Creatures (Snowy Mountains variety) are near the entrance
The following plants can be found near the entrance: 45 Clouded Funnel Cap plants, 8 Milk Thistle plants, and 25 Motherwort plants

 
Zone 1:
thumb|right|351px|Rielle
Upon entry, there's a small room to the southwest containing one enemy and one cask, but the rest of the dungeon is to the northeast. The northeast path soon gives you a choice: you can turn northwest, walk along the balcony of the first large room in this zone (and possibly snipe at the two enemies below), and eventually end up on the floor of the first large room, where you can access one cask. Or, you can unlock the gate at E and continue northeast, giving you a rare chance to meet an Orc Adventurer on the balcony at location O, a chance to snipe at the enemies in the second chamber from the balcony, and access to door C, which leads to the second zone. Going through door C at this time only gives you access to a small part of the second zone, as the rest of the second zone is blocked by a gate that can only be opened from the other side.

From the first large room, there are two ways to get to the second chamber. The stairs in the middle of the southeast wall lead to a walkway above the floor, while the passage from the east corner leads to the floor. The walkway is home to some more undead, another cask, and this zone's boss reliquary (B); however, both containers are located behind pairs of falling blade traps (marked T on map) and gates (F, G, H, and I) that are either remotely opened or triggered to close shut behind you. If you want to stay on the walkway, you will have to jump over the broken section right in the middle of the room. The floor level is home to a high-level ethereal undead, as well as another cask. From the southeast end of the walkway or the floor, you can proceed to the third chamber, which contains three more enemies and two more casks.  Door D at the southeast end leads to the second zone, Crypt of Rielle.

Doors and Gates:
There are three doors in/out of this zone

Zone 2:
thumb|right|267px|Crypt of Rielle
When entering from door D, the first room in this zone is inhabited entirely by ethereal undead, and contains two casks and three Welkynd Stones. The corridor to the northeast leads to an intersection; the room to the southeast has two more ethereal undead and a pair of casks, and the corridor to the northwest leads to the rest of the zone. The northwest corridor is blocked by two gates at F and G that open when their respective pressure plates (cyan dots on map) are activated, but close themselves after you walk through them. The next room contains a ceiling spike trap at T, one undead, and two casks. Continuing northwest leads to the boss chamber.

The boss chamber not only contains the second boss container and the leveled boss undead, but also provides access to a dead-end corridor in the south corner containing another cask and a push block (cyan dot) that opens the gate at E, allowing one to escape this zone through door C. However, the gate will close if you do not make it in time, so be quick to pass through it.
