Boss Battle: Marilith

Marilith resides on the bottom floor of Mt. Gulg, a volcano located on the South Eastern continent, and reachable only by canoe. Much of the floor inside the volcano is covered with lava, as you might expect from such a place, and walking through the lava will deal a small percentage of damage to each of your party members with each step. You can't be attacked while walking through lava, however, so you have something of a choice between taking random amounts of damage from encounters or taking fixed amounts of damage from the environment. Either way, I would argue that reaching Marilith is actually more difficult than defeating her.

My Monk bit the dust about 60 seconds before I reached the boss. As I chose to undertake my quest using a Red Mage rather than a White Mage, I was unable to cast a Life spell to revive him. (The Red Mage cannot learn Life until he upgrades into a Red Wizard.) I'm sure you can understand why I was loath to exit the dungeon, row my way back to town, revive the Monk, row back to the volcano, and climb all the way back to the bottom floor. So I decided I would simply kill the boss with only three players. Marilith is capable of casting Fire II as well as some specialized ability that causes Blind (I can't think of its name now,) but the only thing you really need to watch out for is her physical attacks. She hits five or six times per swing and can deal upwards of 200 damage.

Fortunately for you she has a single, easily exploitable weakness.

Marilith is susceptible to paralyze. It took me four or five tries to figure this out, and another four or five tries to get her successfully paralyzed before she had killed one of my three surviving warriors. Once I got her chained down with everyone still alive, however, I was able to dish out enough damage to kill her before the paralysis wore off. Obviously Ice I and II are the strongest black spells, and hopefully you found the Ice Brand tucked away in one of the treasure chests earlier in the dungeon. I recommend casting Nulfire while in the processing of trying to get her paralyzed, just to mitigate her Fire II spell. Don't be upset if it takes several tries to get your Bind spell to work; it will eventually, and after that she's cake.

Congratulations on restoring your second elemental crystal.
