Gear upgrading refers to the process of upgrading weapons, tools, or armor in order to improve their stats and usefulness to the player. This is the main way of increasing the players strength to allow entry into new, more difficult areas.

• All equipment items have a recipe.
• Item rarities influence both the quantity and quality of possible upgrades.
• Each upgradable item has these possible components:
  • Rarity
  • List of base stats
  • List of active/passive skills
• Not all skills are unlocked at base level.
• Gear upgrades will gradually unlock the skills for a given item and also improve base stats.
• Items of differing rarities will have a different max gear level (e.g. level 5).
• Base stats are upgraded at every level.
• Skills are unlocked at specific levels.
• Skills are not active until its appropriate task is completed (kill 10 enemies).
• Each item has a material list (or recipe).
• In order to upgrade, the recipe is used as the cost to upgrade.
• The cost increases subsequently after each upgrade.
• Skills have an associated material with them, which is factored in to the cost when upgrading.
