All friendly models gain Strider (Water Terrain) for as long as the bearer is alive. Right before the battle (during step 7 of the Deployment Phase Sequence), the bearer must place a single Water Terrain Feature (that must be no larger than 10′′ in length and 6′′ in width) on the Battlefield, not in contact with any other Terrain Feature, more than 1′′ away from all enemy units, and with its centre within 12′′ of the bearer.
