Boon of the Summon System

"The power to call forth allies from across the Omniverse — bound not by world, but by your will."

Core Features:

• **📜 Summon Interface:
  You gain access to a Summon Menu, which allows you to summon creatures or entities from across reality. This includes animals, magical beasts, spirits, elementals, or even iconic characters from fictional/alternate universes.
  You start with the ability to maintain 1 Active Summon at a time.

• 🃏 Gacha Roll (1/day):
  Once per day, you may perform a Summon Roll — draw a card or roll on a table, to receive a random ally. You can spend downtime or resources to improve your odds or target specific summon types.

  • Summons range from common beasts to epic-tier champions.

  • Rarity tiers: ★ to ★★★★★

  • Higher-tier summons last longer or can be made permanent with time.

• **📦 Summon Slots:
  You can maintain a number of stored summons equal to your proficiency bonus. These creatures exist in a pocket dimension and can be swapped in or out with an action.

• **🪄 Command Options:
  You can mentally command summoned creatures, and they act on your initiative. They are intelligent, loyal, and cooperative, though they retain their personality quirks if they’re named/unique.

Growth System (Summon System Rank):

Each time you roll a ★★★★★ summon, complete a major quest with a summon, or win a battle where a summon turned the tide, your Summon System Rank increases (up to Rank 5).

Each Rank unlocks new powers:

• Rank 1 – Novice Tamer: +1 Summon Slot. Basic summons unlocked.

• Rank 2 – Dimensional Caller: Summon creatures from sci-fi, myth, anime, etc.

• Rank 3 – Bond Evolution: One permanent summon gains leveling, loyalty, and equipment. Becomes a true companion.

• Rank 4 – Dual Cast: You can have 2 active summons at once.

• Rank 5 – Legendary Gate: Once per week, summon a Mythic or Divine-level entity for 1 minute. This entity may remain in the world if properly negotiated with.

Card Upgrade (Evolves the Summon)

• Every duplicate summon upgrades the original:

  • ★ becomes ★★, ★★ becomes ★★★, and so on.

  • When a summon reaches ★★★★★, further duplicates grant Evolved Forms, new powers, or alternate skins/backstories.

Optional Mechanics (Pick your style):

• **🔖 Card System: Each summon appears as a glowing card. You can draw, enhance, trade, or seal them. Add a deck-building layer to your character with rare cards, synergy builds, and combo summons.

• **🎲 Summon Dice: Instead of cards, assign dice to your summons (d4 to d20). Stronger creatures are rarer, and critical rolls unlock ultra versions.

• **💞 Affection System Crossover: The more you use or interact with a specific summon, the stronger your bond. Affection unlocks new forms, skills, or backstories. (Yes, like Pokémon meets Persona.)
