Boss Details Helmasaur King

The data below is what's found in the game's code. Sometimes a metadata entry concerns multiple enemies, and certain variables are then rewritten when the enemy is loaded by the game. This is taken into account in the statistics below. On the other hand, some enemies have particular behaviors that are hardcoded and override some of the values below. In such cases, I specify it in the "Notes" box to the best of my knowledge.

The official Japanese name is also given for the enemy when it can be found through an official source. The three main sources I relied on are the game's instruction manual, the official Japanese guide from that era (in its two volumes), the Hyrule Encyclopedia book in its Japanese version, and the game itself (original version). Next to the enemy's number, the name in capital letters is the enemy's code name assigned by the developers in the game's code.

The regional name, on the other hand, is either an official name that appears in an official guide / the English or French game manual, or a name given retroactively because other similar enemies appeared later in the series, or a name given by the speedrun community. If despite all this there is still no existing localization of the name, then I use the Japanese name by default, and if there isn't even an official Japanese name, then it's a brief description.

		Helmasaur King	ジークロック	-
Description			Boss of Palace of Darkness. A giant masked saurian-like creature that can attack either by releasing fireballs that subdivide into 3, then 4, or by delivering a tail whip that covers the entire room. It has two phases: It performs one of the two attacks separately and moves slowly. Link must strike its mask 17 times with the hammer to destroy it. Once the mask is destroyed, its weak point, the large green crystal on its forehead, becomes visible. It moves faster and can now perform both attacks almost simultaneously, making the fight very difficult.
Additional Information			As long as its mask is still present, the only damage it can take is from the hammer (1 HP) or bombs (4 HP). The mask is destroyed when 31 HP remain, and damage then becomes as described in the table below, except for bombs which deal 0 HP due to a hardcoded check.

Does a weapon appear in multiple classes?

In the table above, you can see the Master Sword (level 2 sword) appearing in the rows corresponding to classes 1, 2, and 3. This doesn't mean that the Master Sword will deal random damage determined by these three classes, but rather it's the type of attack you perform with this weapon that will determine the damage it inflicts. If you hover over the name of one of the classes, a tooltip will show you the list of attacks associated with that class.
