Hiding
Danger may lurk behind every tree, deep in darkened dungeons, or simply in the intentions of the rogue walking behind you. With sufficient skill in Hiding, you can disappear into the shadows whenever necessary.
The chance of hiding successfully is directly equal to that of the Hiding skill. Characters may not hide close to creatures that are actively hostile towards them, although at higher levels of Hiding the distance between the character and the monster may be lessened. At GM Hiding, a character may hide in plain sight of a hostile monster or other player only 8 tiles away. Having creatures neutral nearby to a character has no effect on the chances of concealment, just hostile ones.
Like the Detecting Hidden skill, Hiding is always successful within a player's own house. Although this has not always been the case, skill gain will be just as quick as anywhere else.
Unlike the Invisibility spell, the effect of hiding does not wear off and leaves a character safe until they perform another action. Equipping items, looting one's own corpse or moving objects around in their backpack will not reveal a character, nor will the use of the guild/party chat.
Be warned that when successfully hiding while under the attentions of powerful magic-using monsters, they will stop in their tracks and cast Reveal on the character's last seen location. While they are occupied in this process it is wise to consider moving away from that location.
