Samurai Spearmen are a variation of Samurai. They are invulnerable to attack unless attacked with a long-range weapon. Although, you can wage a good battle with Hiro and his power attack. Spearmen can often be found guarding entrances and corners of bases. If you do use Hiro's power attack, be sure you have 2+ "orbs", because, unlike swordmen, they can and WILL stab you during the attack, thus ending the attack. Spearmen will form "walls" to stop you from blowing through.
