Bosses

**Bosses** are aggressive, resilient enemies that offer a substantial challenge to players. Defeating a boss is usually instrumental in advancing the game in some way or another, for example, granting the player a new material for a pickaxe of a higher tier. Each has its own particular way of being summoned. For example, most bosses have associated summoning items that can be used to spawn them manually under certain conditions, while there are others that will appear after the player interacts in a certain way with the environment. Event bosses will only appear during their respective events and leave when the event ends. Mini-bosses also exist and appear only during special events, expressing the same amount of difficulty as many normal bosses.

When spawning into the world with Ruin Mod, you will need to firstly gather resources and fight bosses. The first boss that you will fight that is part of Ruin Mod would be the Gemmonide boss. A Pre-Hardmode boss that players fight after Skeletron but before Deerclops. After that, the next Ruin Mod boss would be fought until Hardmode. The Hardmode boss is called the "Mechanical Brain". Players fight the Mechanical Brain after Skeletron Prime but before Plantera.

Ruin Mod offers a new difficulty mode in which bosses and NPCS are harder to fight! It increases the challenge of the game to even a harder level. To complete any of the boss fights, knowledge of the game is going to be needed.

## Pre-Hardmode

These are the first bosses the player can encounter. Usually, defeating one of these bosses will give the player items and materials necessary to progress in the game, eventually leading to Hardmode.

### Gemmonide [REMOVED]

***The head of a hostile gem lays as a trophy...***

His attacks consist of shooting fire balls at the player and dashing towards him. In Expert Mode, his attacks are way faster and he shoots more fire balls. For Master Mode, he leaves a trail of fire that damages the player. In the For The Worthy seed, the boss's size is reduced by 50%. If you play Normal Mode in the For The Worthy seed, the boss's AI will be in Expert Mode difficulty.
The drops of Gemmonide consist of chances for all of the gem types to drop from him, and a shield accessory that can only be obtained from him.

## Hardmode

Hardmode bosses are significantly stronger than previous bosses.

### Mechanical Brain [REMOVED]

***Reminds you of a long lost boss from somewhere...***

The Mechanical Brain has a total of 2 stages. In the first stage his only attack is to dash towards the player. To enable the second stage, the player will need to kill all of the "Mechanical Brain Cells" that spawn when summoning the boss. In Expert Mode, the Mechanical Brain Cells will shoot projectiles at the player. For The Worthy and Master Mode make the size of the Mechanical Brain Cells be reduced by 50%. When entering the second stage of the boss the Mechanical Brain will be faster and the player is going to be able to damage the boss. The second stage makes the boss shoot a shotgun blast of projectiles at the player. The lower the health of the boss, the faster he will shoot.
The drops of the Mechanical Brain consist of the Rick Sanchez armor set and a "new" type of soul that can only be obtained from him.
