With 8 base strength, Catapult is the heaviest regular Siege unit in the Northern Realms deck. It also has Tight Bond, so placing both copies next to each other doubles each one to 16.
Two copies exist. Buy one from Elsa or Bram in White Orchard, and the other from Marquise Serenity at the Passiflora in Novigrad. Hearts of Stone players have an extra seller too: the elven merchant at the circus camp near Carsten also has one.
Because both copies sit on the same row, one Torrential Rain or a well-timed Scorch can undo a lot of work. Keep a Clear Weather nearby.
