Additions

Informational Items are accessories that display various information on the HUD:

Usage

  • When an accessory is in your inventory, it will display information on your screen.
  • The appearance of the list can be configured and updates live.
  • Server admins can limit the abilities of every eligible accessory.

Obtaining Accessories

  • Informational accessories can be found in Pillager Outposts, Abandoned Mineshafts, Dungeons, and Buried Treasure.
  • They also drop from Raiders, the Minecraft equivalent of Terraria's Goblin Armies. See more below

Raider Armies spawn (on average) every week in-game:

Raiders

  • PDA adds many new raiders by modifying the attributes of vanilla entities.
  • Raiders have custom health, armor, scale, weapons, and more.
  • Every raider has a custom loot pool that they will drop on death.
  • Stronger raiders have a chance of dropping a random Informational Accessory.

Spawning Armies

  • As stated above, armies spawn around every 7 days in-game.
  • Armies can only spawn after at least one player has obtained iron.
  • The difficulty of the spawned army scales with progression:
    • Obtain Iron: Super Easy
    • Obtain Diamond: Easy
    • Obtain Blaze Rods: Normal
    • Obtain Netherite: Hard
    • Ominous Battle Standard: Impossible (Doesn't spawn naturally)
  • Armies can also be controlled using Battle Standards
    • The Warding Battle Standard can stop the current army event
    • The Ominous Battle Standard can spawn an army or increase the difficulty of the current army
      • This is how you can reach the Impossible difficulty
  • Server admins can use the /armies command to manage raider armies.

Reforges are directly ported from Terraria:

Modifiers

  • Every reforge has a set of modifiers that increase or decrease the effectiveness of your item.
  • By default, every modifier is 3 times stronger than the Terraria default.
    • This is because Terraria's weapons are a lot stronger than vanilla Minecraft's and every modifier is a multiplication operation on the total.
  • The strength of every modifier can be configured by admins globally or individually.

Reforging

  • Currently, the only way to obtain reforges is through crafting or looting.
  • The chance an item has a random reforge is configurable by admins.
  • Server admins can use the /reforge command to manage reforges.

Other Info

  • Every rarity was ported from Terraria and is applied to reforged items to change their name colors.
  • Apothic Attributes is recommended for more Terraria-accurate attributes, but it is not required.
