Invisibility for D seconds

This is the other effect (besides Chameleon) that renders you invisible (but not inaudible) to monsters and NPCs in the game. Invisibility is perfect, but temporary. It will end if you cast any spell, attack any NPC, or interact with any NPC or item in the game. There are also a few scripted sequences where an NPC will notice you even if you are invisible.

[edit] Tips

Short term Invisibility effects are useful for getting some easy stealth strikes or for stealing things out of containers and off of store shelves while shopowners are watching you (a five or ten second duration is sufficient for this).
It is not possible to enchant items with Invisibility as the effect does not appear in the list when using an Altar of Enchanting. The reason for this is because, if you use the Construction Set to make the effect available for enchanting, you will become invisible, but the effect will be dispelled as soon as you do anything but move, requiring you to reequip the clothing. This is why there are no pre-enchantments or Sigil Stone in the game.
If you go invisible, there will still be a small outline for you to see. The characters in the game cannot detect this, but you (as opposed to your character) can. When an NPC goes invisible, you can look for this outline to find them without the aid of Detect Life.
An invisibility spell with a duration of up to fifteen seconds only requires an apprentice level in Illusion; however, the only way to obtain the spell effect before journeyman level is being born under the Shadow Birthsign, or to become a vampire and rest until you have 100% vampirism.
