The update additionally reworked many mechanics such as the Rage Meter, changed core-vanilla Terraria mechanics such as Goblin Tinkerer's reforge system and movement speed bonuses, and resprited a plethora of textures including a complete visual overhaul of Supreme Calamitas and the mod icon. It also added Malice Mode along with several other game mechanics, and numerous items ranging from weapons to vanity items. The 1.5.0.001 (or 1.5.0.1) update, also known as the "Draedon Update", added The Codebreaker and a boss battle with the Exo Mechs featuring Draedon.
