4Obscure API is a technical mod that contains the code necessary for other mods to work.

Features:
Class Equipment:
- The ability to assign a game class to an item (for example, Necromancer), which is displayed in the item description.
- Class armor can have custom bonuses (for example, “-30% Cooldown Duration for Necromancer Class Weapons” or “30% Ability Power for Necromancer Class Weapons”).
- While the armor is equipped, its bonuses apply to all items that match the description.
Weapon Abilities:
- Any weapon can be assigned an ability that includes a Passive Effect, an Attack Effect, an Active Effect, and an Extra Active Effect.
- Each effect can be assigned a cost (Cooldown, Item Durability, Player Experience, or a custom cost).
- The value of the effect cost and effect strength dynamically change in the item description if you have the appropriate class armor bonuses.
Item Upgrades:
- The mod adds materials to the game that can be used to upgrade items. You can add material functionality to your own items.
- Each material has unique properties and is applicable to items of different types and levels.
- With the help of materials, you can upgrade any equipment up to [Item Name] +10, increasing the main attribute (Damage for weapons and protection for armor). Changes are visible in the item tooltip.
Attribute Display (Client-Side only):
- Equipment displays its attributes in the tooltip using icons (can be disabled in the config (Obscuria/obscure-api-client.toml)).
- Food displays its properties in the tooltip using icons (can be disabled in the config (Obscuria/obscure-api-client.toml)).
Extended item descriptions (Client-Side only):
- You can add lore lines to any items by their ID.
- You can add knowledge lines to any items by their ID (The text is hidden if the player does not have the “Knowledge” effect).
“Hekate” Animation Library:
- A simple pure math library that uses Obscuria mods to animate creatures.
