All about The Giant Sea Serpent

 What is it: 

The Serpent is the main boss of the game. The boss has 1000HP, and it's very strong and can kill you in just a few seconds if you are not prepared.

 Its attacks: 

It can do 1 of 2 attacks:


 * Charge attack. It rushes towards you, pretty simple. The distance, speed, and amount of times it charges are random, so keep on your toes.
 * Electrocuting the water. Whenever it's resting below the spawn platform, it will stand mostly still while electrocuting the water. Stepping into the water will deal 5 damage to you every half second.

 What happens when it is killed: 

When it is killed, it will drop rubies (which do not have practical use) and a ladder will appear in the middle of the map. This ladder will take you back up to the cave. When you finish the game by building a boat, you will get a different ending than if you didn't defeat the boss.

 Where can I find it: 

To find it, you first have to go underground and take out your map. On the map, you want to look for a black ring with a brown square in the middle. When you go to the black ring, gem ore will be blocking you from going down the ladder. Once you break the gems and go down the ladder, the boss will start fighting you and you appear in a new map. WARNING!!! Once you go down the ladder to fight the boss, you can't come back up before defeating the boss. DO NOT go down until you truly feel that you can kill the boss.

 How to defeat it: 
 * Bring a gem sword. The gem sword does more damage than any other sword, making it perfect for dealing damage to the boss.
 * Bring potions. One potion will revive your health all the way. With the boss constantly attacking you and you always being seconds away from death, it's important that you have these potions to instantly heal yourself up.
 * Bring the Talisman. The Talisman freezes the boss for 10 seconds, giving you a chance to do major damage to the boss. It's important to remember that you can use the Talisman an infinite amount times.

 Trapping the boss: 

It is possible to trap the boss, making it really easy to deal damage:


 * Wait until the boss is done electrocuting the water. If the boss charges at you right after this, it's not possible to trap it.
 * Walk straight up to the 3x3 block of red stone material and stand slightly above and left or right of it, and wait for the sound cue of the boss charging at you.
 * When its head reaches the red stone, run across the top, then down, then diagonally down so that you're under the blocks. If done right, the boss's head should be stuck up top, and any attempts it makes at charging at you make it ram into the wall.
 * Wait until it tries to return to its starting position. The serpent's body should now be stretching down, but the head will stay up top, forming a sort of line.
 * You're now able to hit it as long as you want. Keep in mind the water will still be shocked by the serpent, so going down to the spawn platform will make cheesing the boss a lot easier.

If you want a visual on how to do this, there are multiple Boss Kill% speedruns available to watch that utilize this strategy.

Worth noting that using this, it's possible to skip a ton of stuff. Who needs a sword, healing, or a talisman? Fun fact, though: No one's beaten it like that before.

Another way to easily defeat it is to use the talisman when it gets close to you, hit it with your gem sword for a little bit, then use the talisman again once the boss can move. Heal yourself and then repeat this strategy until the serpent is slain.

The Two Endings:

If you place a boat before slaying the serpent, you win, but with the text: "You escaped, but the monster still lives.". If you defeat the serpent, and THEN place a boat, you get a better ending, saying: "You escaped in a boat full of treasure." with the same end art as the normal ending, except with a pile of rubies in the boat  (more on those at the top of this page).
