Boon of the Inventory System

"You’ve unlocked a personal extradimensional inventory interface, complete with categorization, time-stasis, and hidden functions yet to be revealed."

Core Features:

• 📦 Infinite Storage:
  You gain access to an invisible, extradimensional inventory that only you can access. You can summon or store any object you are holding or touching as a free action. This space can store an unlimited number of non-living objects, regardless of size or weight.

• 🕰️ Time-Locked Items:
  Objects stored in the inventory are placed in stasis—they do not age, degrade, rot, or lose potency. Food stays fresh, potions retain power, and even flaming torches remain lit (until pulled out).

• 🔍 Auto-Sort and Retrieve:
  You can name, tag, or categorize items mentally. Retrieving a specific item is always instantaneous, even in combat.

Hidden Mechanics (Growth Unlocked with Use):

• 🛡️ Auto-Equip Function (Unlocked after storing 50 different items):
  You can swap any equipped gear (armor, weapons, accessories) with another stored version as a bonus action. You can also automatically equip optimal gear in a situation (based on tags like “fire resistant” or “aquatic combat”).

• 🌀 Emergency Recall (Unlocked after your first unconsciousness):
  If you would drop to 0 HP, your inventory can automatically activate a stored item (like a healing potion or magic scroll) as a reaction. Can be used once per long rest.

• 📥 Storage Capture (Unlocked after storing a legendary item):
  You can attempt to absorb an unattended object within 60 ft into your inventory as an action. This includes thrown weapons, magical items, or even falling debris. Make a spell attack roll vs the object’s AC (or a DC set by the System).

• 💾 Blueprint Mode (Unlocked after analyzing a crafted item):
  If you study an item for 1 hour (or disassemble it with appropriate tools), you store a “blueprint” of it. You may attempt to recreate it exactly using raw materials. Roll with advantage on crafting checks for items stored this way.

• 🧩 Stacking Function (Unlocked after storing 100 of a single type):
  You can combine identical items into stacks (e.g., 100 arrows into 1 “arrow stack”) and deploy them en masse, like “throw 10 spears at once” or “drop 50 caltrops.”

Optional Expansions:

• 📦 Summon Inventory Construct: You can summon a semi-autonomous magical helper made of item projections (like a floating armory orb or mimic servant) that carries, sorts, or launches gear.

• 📜 Multiversal Database: Rare artifacts from across the Omniverse sometimes appear in your inventory with vague descriptions, hinting at events or powers from other realities (e.g., a Hylian Hookshot or Captain America's shield).

• 💻 Interface Evolution: After a major milestone, you gain an actual HUD only you can see, showing HP, inventory weight, and item info. Dialogue boxes may appear during critical moments.
