New NPCs

Players can also interact with and invite many new NPCs to their towns. These new NPCs include:
  • Agent: A unique vendor that isn't actually a town NPC. Gives players random items based on their progress in the game so far.
  • Arc: A Hardmode NPC who sells items like the Muramasa, Blue Moon, and Aqua Scepter.
  • Archmage: A Hardmode NPC selling various items that can inflict the Glacial State debuff.
  • Bandit: Sells items befitting for the Calamity mod’s new character class, the Rogue.

Rogue Class

Players can choose between four different character builds in vanilla Terraria: Melee, Magic, Ranged, and Summoner. With the Calamity mod, however, you can now also become a Rogue. As a Rogue in Terraria, you take advantage of stealth to deal damage and kill enemies. Rogue-specific armor sets will also grant you a Stealth Meter, which increases or decrease based on different parameters. At max stealth, the character becomes transparent to the point that the model is almost invisible. If the player is in full stealth, the character can use the Stealth Strike attack.

New Crafting Recipes

Many items in vanilla Terraria aren’t accessible other than killing enemies or getting lucky opening chests. Install Calamity mod, and many of these vanilla items become accessible through crafting as well. For example, before, you could only get the Cloud in a Bottle by opening gold chests underground. With the Calamity modpack installed, you can craft this item as well.
