World objects are objects that spawn randomly at each dungeon and can be interacted by the player and, sometimes, monsters.
Chests: Chests are solid blocks that contain loot or may occasionally be a Monster-in-a-box. Wood Chests can be open normally, while Gold Chests require a key to open.
Doors: Doors are solid blocks vision until opened, can be closed, and there is the locked variant which can only be open with a key
Crates and Barrels: solid blocks that can be destroyed and may drop loot.
Portals: Portals are non-solid blocks that, when interacted, will teleport you to another Portal. Notice that they work in pairs, so, there won't be an odd number of portals in the dungeon level, and, when using any of them, you will always go back to the corresponding pair.
Bookshelves: solid blocks that when interacted, will rarely raise one of your stats.
Traps: Traps are found in the ground, and when stepped by a monster or a player, they will activate their function. It can be Poison, Fire, Stun and Spikes. The player can interact with it to, with a chance based on your inteligence and your Identifier Talent, disarm the trap and receive experience.
