## What Is This?

7 Deadly Sins Card Game is a free-to-play, browser-based strategic multiplayer card game where 2-4 players each embody one of the seven deadly sins and battle in a gothic cathedral setting. The game features 7 playable factions, 84+ unique cards, compound mechanics that escalate over 20 rounds, AI-powered narration, and deep strategic depth inspired by games like Slay the Spire, Inscryption, and Magic: The Gathering.

## Core Game Mechanics

### Factions (7 Deadly Sins)
Each faction has a unique passive ability and 12 cards:

- **Wrath** (Ira) — Passive: VENGEANCE. Reflects damage back to the attacker. Aggressive, high-risk playstyle.
- **Sloth** (Acedia) — Passive: ENDURANCE. Generates shield and AOE damage from stored energy. Defensive, attrition-based.
- **Greed** (Avaritia) — Passive: TAX. Damage ticks generate protective shields. Resource accumulation playstyle.
- **Envy** (Invidia) — Passive: JEALOUSY. Dealing damage deepens the target's worst affliction. Debuff-focused.
- **Pride** (Superbia) — Passive: HUBRIS. Playing the most expensive card amplifies all effects. High-cost, high-reward.
- **Lust** (Luxuria) — Passive: TEMPTATION. Damage over time heals you as it hurts them. Sustain and drain.
- **Gluttony** (Gula) — Passive: DEVOURER. Destroying enemy cards feeds your energy. Disruption and consumption.

### Card Types
- **Flat cards**: One-time powerful effects (immediate damage, heal, shield)
- **Compounding cards**: Weaker base value but tick for 3 rounds with Fibonacci scaling (1x, 1x, 2x). Types include damage-over-time (DoT), heal-over-time (HoT), shield-over-time (SoT), and steal effects.

### Energy System (Corruption)
Players spend Corruption energy to play cards. Energy regenerates each round. Each faction has unique energy interactions tied to their sin identity.

### Win Condition
Last player standing after up to 20 rounds of combat. Players start with 100 HP.
