Invisibility

''This article is about the general game mechanic. For Wizard's spell by the same name, see Spells.''

Invisibility turns any given hero transparent and hides them monsters' sight but grants no physical protection. Invisibly, unless invoked through Dryad's Flute, is denoted by the affected heroes taking a spherical light-bending form and is revoked upon using any attack or dodge. Any hero that is invisible may safely pass through Death Incarnate but are still susceptible to taking damage from any other attack; if all alive heroes turn invisible simultaneously while Death Incarnate is present, it will despawn.

Ordinarily, indivisibility does not render the subject intangible, however, the Ghost Orb relic provides an exception to the user. Any hero who invokes invisibly by means of a Ghost Orb will be able to phase through any monster or prop. Fellow heroes within a small radius will also be made invisible when a Ghost Orb is used, but will not be granted intangibility.

Keep in mind that only heroes can become invisible. This does not include any entities that may be of aid to heroes but are not heroes themselves, such as illusions summoned by Ring of Mirrors, gargoyles summoned by Demonic Effigy, any monsters charmed by Siren's Lute or Scepter of the Vampire King, or any minions summoned by Necromancer. This can be a particularly important fact to realize when in the presence of Cultist Sorcerers, for example, because they may attempt to cast a hex upon these aids. They will be unsuccessful in doing so, however, because hexes attempt to target all heroes and their allies simultaneously, heroes will also be targeted regardless of their invisibility. Because of this and akin situations (like when fighting a Lich or Demon Horror), it is often advisable to avoid using invisibility in conjunction with any of the aforementioned assists unless you can easily respond to any threats that may arise.

Glitches

 * By using Ghost Orb and Shadowstrike together, Elf is capable of staying invisible indefinitely. To do so, activate Ghost Orb and before it wears off, activate the Smoke Bomb ability of the Shadowstrike bow. Repeat the use of the Smoke Bomb for extended invisibility.
 * Wizard can have invisibility applied to him by another hero via Ghost Orb while he is channeling various spells, such as Ice Beam, Hellfire or Dark Torrent.
