Bosses

The Tremor Mod expands on the number of bosses that can be challenged throughout the game, each featuring memorable, challenging AI and unique, powerful drops. Most require the use of boss summoning items in order to spawn, but others have more unique prerequisites. The initial defeat of bosses (both vanilla and Tremor) typically results in some form of change within the world, be it new enemies appearing or a meteor crash, indicated by status messages to direct players towards the new content. The mod currently adds twenty four new boss encounters.

In Expert Mode, bosses drop Treasure Bags which contain powerful Expert-exclusive items in addition to their normal drops. However, many bosses also have new and unique attacks providing players with new challenges to surmount if they hope to reap the rewards.

Most bosses in Tremor are designed to be about the same difficulty as those of vanilla Terraria, presenting a large challenge to the unprepared but are not required to progress through the vanilla game's content. To make up for this, they often drop more powerful equipment and open up new tiers of progression.

After the player has killed the Moon Lord, a whole new level of progression is unlocked, containing several very powerful bosses that will push the game's mechanics to their limits. These serve to test the player's skill and game knowledge and allow for additional tiers of weapons and items beyond what Terraria's endgame has to offer.

Unprepared players will find these bosses to be spectacularly difficult, but if precautions are taken and proper preparations are made, all of them can be defeated at their respective level of progression. Players are advised to make use of arenas, potions and any other kind of aid they can muster before confronting these challenging bosses.
