Path to Power 1.0-2.0 Phantom Item is an informal term for any tool or object that a player character is shown using inside the comic but that the clan didn't actually make or acquire. For example; if the healers are shown using blankets but those blankets are not listed under the clan inventory then they would be considered phantom items.
Relying on these items is ill advised since as their name implies they tend to disappear at the most inconvenient time.
Path to Power: To the Sky
With the focus of Path the Power shifting from colony building and industry to adventure phantom items have become more commonplace. Most mundane items are assumed to be available with specific items such as "Relic Hunting Gear" and "Summons" (Soulmirs) having to be found or traded for.
