Through your journey into the Labyrinth you can find different kinds of objects which are, more or less, tied with the gameplay. I will try to describe some of them below:
Stairs are used to move between the levels. They are divided into exists and entrances that differ in the look. The graphic of stairs also depends on which location they are in. The below picture shows the stairs in Dungeon (on the left) and Hell (on the right) level.
Sarcophagus are places in the first four levels of the dungeon. We can open them by clicking on a sarcophagus. Such vault can hide gold, items or can simple be empty. Also after opening a sarcophagus a skeleton can come out of it which we will have to fight. In the King’s Leoric Tomb there are some sarcophagus that cannot be opened.
In the dungeon underneath the Cathedral there are many barrels we can break. They can hide gold or other items. Some barrels explode after breaking them by which out character can receive damage. Apart from explosion, we can be threatened that the barrels is hiding a skeleton which after the release will stand against us..
In libraries you can find books with knowledge of magic. The tomes located in libraries contains spells which we will be able to learn or increase our knowledge on a given spell.
Nearby libraries Skeleton Tomes can be found with a scroll or a magic book on them.
Tomes on Pedestals
In the labirynth we can find massive Tomes lying on stone pedestals. The tomes contain information related to the dungeons and the history of Sanctuary – the universe in which Diablo takes place.
Chests similar to sarcophagus are places all around Cathedral’s dungeons. They are divided into small chests, chests and large chests. Every trunk can contain an item but that may not necessarily be the case. Small chests can contain only one item, normal chests can hold up to two items and large chests can hide three items.
Located in King’s Leoric Tomb, if we set them lose, a hidden room will now be open which contains magic items.
Shrines have magical effects, sometimes negative so they are to be used with care.
Burning crosses are placed in small rooms. If you encounter such a room, be careful as touching the burning cross our character will get burnt and loose some of its health points.
Levers are used to open rooms.
Is located on the 5th level and is related to the “Valor” quest. We have to put three Bloody stones on it.
Hanged and nailed bodies
These are massacred human bodies. Can be found in great number in on level 2 in the Butcher’s room. In addition can be found on Hell levels.
Bodies in Butcher’s Room
Equipment stands – located on Hell levels.
Located in Lazarus’ Room. Body of a scarified child lies on it.
Decapitated Bodies and Slain Hero
Decapitated bodies are the bodies of heroes who went deep into the labyrinth to seek treasures. Slain hero – it’s a body of a hero who died fighting evil.
Located in the first levels in Dungeon
Magic circles can be found in Arch-bishop Lazarus' Lair and only in single player mode. They are located by Tomes of and of them will teleport us to Lazarus.
In Diablo we can also encounter naked bodies of woman strapped to walls ;)
They illuminate our path in Dungones.
In single player on level 9 a mashroom patch may be found, it is related to Black Mushroom quest given by Adria
Doors are entrances to rooms in the labirynth. While running away from a monster, we can close them after us so we cutting out his route. Unfortunately, some of the monsters can open doors and block them making it impossible to close them.
Through the bars we can see monsters in another room, it is also possible to shoot arrows from a bow or using spells on monsters while out character is behind bars
There are many traps set in the dungeon. They can be set on chests, sarcophagus or on doors. Traps take form of a spell or a flying arrow. Trap shells are in the walls.
A portal is created with a help of a spell and we can use it to help us getting from the dungeons to the Town and back again. Portals places by us are blue. In the game there also is a red portal available, that takes us to the headquarters of Archbishop Lazarus
The Great Pentagram
On level 15 of the dungons there is the great portal. It is placed on the ground and is used an entrance to level 16 where Diablo The Dark Lord is located.
