Model gains Tunnel. Before making this model's normal movement, you may place a tunneling marker anywhere within 5" of this model and remove this model from the table. Remove effects (other than Tunnel) on this model when you remove it from the table. In your next maintenance phase, place this model anywhere within 5" of the tunneling marker and remove the tunneling marker from the table. If there is no where to place this model on the table, this model is removed from play. Tunnel lasts one round. A model may not gain Tunnel in a round after it has gained Tunnel.

"Tactical Tips"

When using Underground, effects removed include upkeep spells, other spells, continuous effects, animi (enemy animi, since friendly animi would already be replaced with Underground) and other effects (like dug in). Fury points and damage taken are not removed. Note that removing a warlock from the table will cause all of their upkeep spells to drop and their warbeasts to go wild.
