Mt. Siz is the second area in the Scenario area of the Battle Map, and is available to players after completing Garen Forest in normal mode. The terrain is mostly rocky, and is inhabited by a variety of Golems, among other Monsters.
After settling down the monster outbreak in Garen Forest, Lycana mentions that the Magic Council has discovered Ancient Ruins in Mt. Siz. She also reports that there are sightings of Golems in the area. Lycana then asks for the player's help in examining the ruins.
The first few stages are filled with normal monsters that are defeated easily.
At Stage 4, Golems start to appear. These monsters have high defense and has a skill that reduces incoming damage by 40% when they have less than 50% HP. While defeating them will take some time, their Attack is not high.
In Stage 7, the Boss sized Golem (Fire) does not appear with two underlings as most bosses do. You'll be at an advantage if you have any skills that can reduce the defense stat of the boss or if you have monsters with skills that will inflict Continuous Damage as it is a harmful effect will always to 5% of the enemy's MAX HP per each turn, bypassing the Golem's high defense stat.
