Gondorian spearman is a very good chump blocker. He's fairly cheap, and can attack a bit before you need him for defense, or quest with visionary leadership. With Thalin and a spear of the citadel, he can take out 160 of the game's 531 enemies. Get a few of these out, play a stand together and hold the line, and watch as the enemies go down.
Response: After Gondorian Spearman is declared as a defender, deal 1 damage to the attacking enemy.
Core Set #29. Tactics.
I don't know about this guy. You're paying 2 for an ally that's constantly in danger of getting killed, and once you're past the first cycle's swarms of bats and crows, there's not many things he can one-shot. He's in a strange place between disposable and important. It is enticing to build an elaborate system with Thalin, Spear of the Citadels and Honour Guards, but at that point you could just have a bunch of normal allies doing normal fighting. Always feels good when the enemy's last hit point happens to line up, though.
