Rune Items
(Rule)Description: An Ancestral Heirloom or runic item is no different from a magic item, and all the usual rules for magic items still apply. For example, a creature with Ethereal rule cannot be hurt by attacks that are not classified as magical- in which case a runic weapon will also be able to affect it. All the rules that apply to the possession and use of magic items also apply to runic items.
Note that a shot from a war machine with an engineering rune is a magical attack.
