🕹️ Game Design

Loot Survivor is an onchain Arcade machine game. You add some tokens, try to get the highscore and live for eternity onchain.

Each play through will be different and there is no end to the game. Every level just gets progressively harder.

Game Statistics

Each level up grants adventurers 1+ upgrade to help them survive their explorations. Although Luck cannot be upgraded directly, it can be increased by equipping jewelry items:

• Strength: Boosts attack damage by 10%.
• Vitality: Increases health by +20ph and max health.
• Dexterity: Improves chances of successfully fleeing.
• Wisdom: Helps evade Beast ambushes.
• Intelligence: Aids in avoiding Obstacles.
• Luck: Raises chances of critical damage (cannot be upgraded directly).

Combat Logic

There are three categories of weapons and armor materials:

Weapons: Blade, Bludgeon, Magic

Armor materials: Cloth, Hide, Metal
