However, by belonging to this genre, it evidently anticipates that we will eventually run into some bosses.

These enemies cannot be confused with the rest of the opponents and monsters that you will run into on the way, since they have clear differences.

Although they are mostly available in the currently supported versions of the game.

Bosses in Terraria: what they are and how they differ from common monsters

As in other games, the Bosses in Terraria, also known by the community as « Bosses» , coming from English, are a special type of monsters, which have much higher statistics than the common opponents that you can find in any Biome. . This means that they are much more powerful, with a higher damage potential and more resistance.

But this is not all, since once you manage to defeat a Boss in Terraria, he will drop some object or item of value that you can use for some purpose on your journey . Another difference compared to common enemies is that the Bosses are not in any type of Biome, but certain specific conditions must be met in order for it to be invoked. In some cases, you must obtain a specific milestone, assassinate a character, or perform a summoning ritual.

It is important to note that the Chiefs increase their offensive and defensive stats further as the difficulty of the game intensifies. This means that the Bosses you face in Normal Mode will be weaker compared to those in Hard Mode and these, in turn, are not as strong as those in Master Mode .

A relevant detail to mention about the Bosses of Master Mode is that when you defeat them, they will leave you as a reward some valuable relic for your pets or special mounts . This is something to keep in mind, but they require a lot of strategy.

It is also important to mention that when you have met the conditions for a Boss to appear, a status message will immediately be displayed announcing their appearance, but their soundtrack will also begin to play . But the exclusive event bosses do not have these signals, so you must be aware of what happens on screen.
