"In Honor of Our Fathers"; - "Wisdom of the Earth" [Campaign 3, Mission 4]

Maximum level - 26. The Warriors actually buried Prince Andrias (you can learn about him in "Hammers of Fate"), whom Biara sacrificed to prevent the artifact, the Griffin's Heart, from sending demons to Shi'o, and instead summon them. And how did you take the Temple? There are ten colossi, a bunch of elementals, and others. They kill Kujin easily. Artifacts are not passed on to Gotai. Most likely, you found him similar artifacts in the third mission and forgot. Also, I advise you to equip Kujin with artifacts that are most useful for storming the castle, and sell the rest in the Factory. The fact is that in the last mission (if you haven't reached it yet), Kujin will have to fight a demon that has settled in the castle, and there will be no time to change the artifacts (if the game version is 3.1). If the game version is 3.0, then Kujin can be stopped, and then Gotai will go into battle with nine hundred cyclops. In 3.1, the heroes in this mission cannot be stopped, and the orc has only one goblin in his army.
