Siege Tower adds 6 strength to your Siege row and has no special ability. It’s a reliable mid-strength card for a Northern Realms deck that builds around siege engines.
Only one copy exists, and there’s no fixed seller. You get it as a random reward for beating generic gwent players like merchants, innkeeps and villagers.
Torrential Rain drops it to 1, so pairing it with a Clear Weather card or Foltest: Lord Commander of the North is a good idea. See Collect ‘Em All for more on hunting random cards.
