Battle for Wesnoth

(Cantrip – Mythic Tier) - This cantrip is treated as a 9th-level spell when cast. You tear open a rift in space itself. This portal is absolute — unsealed by force, unblocked by magic, and untraceable by any divination. As an action, you can open a portal to any previously visited location, even across planes or dimensions. You and any number of willing allies can travel through the portal instantly. The portal remains anchored for as long as you wish, allowing free passage both ways. This Gate cannot be blocked, countered, sealed, or dispelled by any magical, divine, or planar ward. Once opened, you may maintain the portal indefinitely without concentration or restriction, and you can choose to close it at any time as a free action. While this spell is active, you are considered to be under the effect of a non-detection ward, and any attempts to track, scry, or teleport to your location automatically fail.
