I belive the Sacred Warrior means the Kiron.
Kieross asked Kiron to accept the fate and disappeared in Catacombs. Kiron now needs to meet Ancient Stone Slab at Catacombs 1 which only needed him to go W.
There the Ancient Stone Slab needs Kiron to kill 25 Blaze Lich and 25 Strong Blaze Lich in the same map.Next Kiron needs to defeat the attack from 25 Expert Thunder Harpy and 25 Master Thunder Harpy.It took Kiron a long time to kill all the Harpies, but then the Guradian Scorpions come out , defeat them also!!
The Scorpions are hard and Kiron needs to be award of their poinson. Now here comes the Challange from the ICE, Kiron needs to beat 25 Ice Pick Lich and 25 Strong Ice Pick Lich. After the ice attack, Kiron faces the Gnolls now, kill 25 Metal Armored Warrior Gnolls and 25 Plate Armored Warrior Gnolls.
The Lightening Harpies come after the Gnolls with the same amount, Kiron should kill 25 Electrified Harpies and 25 Strong Electrified Harpies. And finally Voila, Kiron meets the Boss the Guardian Fire Golem, defeats it.
Now Kiron finally arrived the Alter, next quest for Kiron is to defeat the Guardian Ice Golem which is in Catacombs 10. Knock the 3 organs to open the way back to Catacombs 7 and goes W-W to the destiny.
Behind the Guardian Ice Golem, Kiron meets the Kieross who has just brought back the ancient god, now Kiron's opponent will be the god.
The Ancient God is quite tough as the Boss, Kiron needs to see the circle under the boss, when it turn to another color, Kiron needs to hit the column with the same color, and afterwards it will block all Kirons attack ,that time Krion needs to get the buff from the column with green color.
And now we beat the Game of Exitium: Saviors of Vardonia with the Character of Berserker Kiron.
Hope you like my walkthrough.
