In the original version of LEVEL 4, the first stage ogre leader had two skeletons. This indicated that CoM's apprentice was a difficulty that did not exist in the original.

CoM also fixes a freezing bug that occurs in combat with the Black Dragon. However, it is wise to avoid this bug during speedruns, as it extends the time that the Black Dragon will fall if the conditions for the bug are met. Condition of the bug: Defeat the Black Dragon at the moment it spits out its breath.

In the meantime, the "CoM I am planning to prepare three leaderboards: "CoM", "ミスタラ英雄戦記" (PS3), and "Arcade and Emulator".

I will check the difference in difficulty between the arcade version and CoM at a later date and write again.

The usefulness of skipping the mud golem is questionable for the following reasons

During the cutscene the elf is defeated by the mud golem. The game is over and the player loses items, including magic weapons and the Gauntlet of Ogre Power.

The strategy of losing items including game over should not conform to a quick clear, so I was not concerned about the difference between platforms.

Sorry for reply late. And thanks for asking new category. I've added new category. Do you have more details for rules ?
