Setting

In its early years, Tibia took place in a medieval Tolkien-esque setting, but as years passed and new areas and content were added, inspiration was drawn from a wide range of fantasy, mythological, and historical influences, resulting in a diverse world of many continents, with seventeen major cities. NPCs have unique dialogue and responses to keywords provided by the player. NPCs can buy and sell items, give quests, provide information and hints, and tell stories. The world also contains many books and libraries that contain information, quest hints, tales, and history about the world of Tibia. Tibia contains many allusions to the outside world, including pop culture references, allusions to video games and books, mythological references, and more. The demonym of a Tibia player is Tibian.

Combat

Tibia has hundreds of weapons and armors used for fighting and protection from attacks. Melee fighting is the specialty of knights, who may choose to advance their sword, axe, or club skills, and who may also wear a large variety of armors and shields. Melee attacks only hit monsters on squares adjacent to the attacker. Ranged fighting is the specialty of paladins, who attack using an assortment of bows, crossbows, and throwing stars. Ranged attacks can hit monsters from many squares away, and different weapons have different attack ranges.

All four vocations can use magic to some degree. Sorcerers and druids have a wide variety of magic spells available to them, while paladins and knights have a limited variety. Tibia's magic system is text-based. There are two types of magic: instant magic and rune magic.^[8] Instant magic uses spells that, once cast, will consume mana in order to produce the desired effect. Each spell uses spell words and consumes some of the character's mana points to use. Some spells are offensive and deal damage to creatures, some heal the player, and others serve other purposes. To cast a spell, a player can type the words of the spell into the text channel. Typing "exura gran" casts the Greater Healing spell. Tibia's client developed over the years to make spells easier and quicker to cast using hotkeys. Players may assign each spell to a hotkey, and press the hotkey when they wish to cast it.

Rune magic is magic cast by using an item called a rune. Runes are magic spells stored in small stones. To create runes, a player casts a spell while holding a blank rune in their inventory. Casting the spell "adori mas flam" consumes 530 mana and turns one blank rune into four "Great Fireball" runes, which may be stored in the player's inventory and then used later. Players may buy both blank runes and spell runes from vendor NPCs, along with mana and health potions to restore hit points and mana.

PvP

Players in Tibia are allowed to attack and kill other players. The rules governing PvP vary depending on the player's server type. Some servers, called Optional-PvP, don't allow player killing except under certain circumstances, while other server types, such as Hardcore PvP, encourage such fighting. In Tibia's early years, players could kill any number of players without limits, and players who died lost a portion of their experience and dropped their backpacks and equipment. For this reason, Tibia earned a reputation for being a punishing, unforgiving game. Over the years, PvP rules were adjusted and modified, and a complex system is known as the "skull system" was implemented on Open-PvP servers to limit player killing. Many items and resources in Tibia are limited, and many intense large-scale wars have been fought in Tibia to decide who gets them.

Houses and guildhalls

Players are allowed to purchase houses and guildhalls in Tibia's major cities. The houses sit in the view of those walking by, and players often decorate their houses in various ways. Some players display their rarest items, and others decorate their houses with roleplaying items such as tables and chairs.

Phasing out of Game Masters (GMs)

In late 2010, CipSoft decided to phase-out the "Game Master" system which had been used since launch. The Game Masters, commonly known as "GMs" to the community were well compensated for their time with a rare item of their choice. CipSoft implemented a new report statement function to the game client that players could use themselves, and the official course of action is for customer support to deal with all game queries. These representatives can be noted on the game's forum boards as Community Managers, or "CM" for short.

Level 999

In 2005, a Tibia update added a door that requires a player to reach level 999 before it opens. The level 999 door remained a mystery until August 2016 when a player named Kharsek, the first player to reach level 999, entered the room.^[14] Kharsek, however, chose to keep their discoveries behind the door a secret, and the general public had to wait another ten months to learn the answer to the mystery of what lay behind the door. In June 2017, a player named Dev onica broadcast a live stream via their Twitch account, where they entered the level 999 door at level 1,001; they were transported to a tropical island with a variety of NPCs and no additional content of note.^[15]

Rule violations

Conduct from players and premium accounts are expected to abide by rules rather similar to most such games, including prohibitions against sharing or selling account information, exploiting "obvious" errors or flaws which give unreasonable advantages to a player, posing as CipSoft employees, using any and all non-official programs such as "bots", and offensive behaviors. In such events, CipSoft uses a system of a violation record and conduct levels that grade both the severity and frequency of violations, with the "conduct level" slowly relenting over time with no new violations. Once a violation is entered in the record it can be protested until 60 days have lapsed, allowing players to protest inappropriate charges or complain if the charges are not understood; the entry cannot be expunged from the record later than that time. If the conduct level reaches its highest state, whether through continued minor violations or few very severe ones, the account is threatened with banishment (from the game and forum) or deletion.^[17] If an account has been banished or scheduled for deletion, CipSoft promulgates that the only recourse is to either create a new character or appeal to Customer Support directly.

By January 2009, CipSoft banned 4,959 characters for using illegal software while playing.^[18] A quote from CipSoft at the Tibia website states:

These accounts have been identified by an automatic tool with complete accuracy, therefore any complaints about these punishments are in vain. They are final and complaints will be ignored. We will neither reveal our criteria for these punishments, nor will we hand out any proofs.

The article goes on to say that CipSoft is not finished and will continue to work hard to eliminate cheating from the game.^[19] Since then, CipSoft has used this automatic tool about once a month to delete tens of thousands of accounts.

In September 2010, CipSoft made fundamental changes to the player versus player fighting mechanism, in an effort to mitigate abuse.

CipSoft implemented the anti-cheat software BattlEye,^[20] launched on 18 April 2017, with retroactive protection to other game-worlds over the course of a year.^[21]
