Advanced Cloaking is a special ability available to the Resolute Class Battlecruiser and the Dark Wing Class Battleship in regular games, and the Deth Specula Heavy Frigate and Red Wind Storm-Carrier in campaign games.
Unlike a regular cloaking device, this device does not burn fuel in order to cloak, it protects the ships from ion storms while it is active, and can even be used inside Nebulas. It does not grant any of these ships protection from a Loki, so any of these ships under the control of a non-Loki Immune race will still be decloaked if a Loki is nearby
Ion storms will not affect ships with advanced cloak, as long as the cloak is engaged. They will not be dragged, decloaked or damaged.
