Armor upgrades in Remixed Dungeon enhance defensive capabilities through various mechanisms.

The Scroll of Upgrade can be used on any armor piece to:

• Increase the armor's level by +1
• Remove curses from the armor
• Potentially add or remove a glyph (random chance when armor has no glyph)
• Increase defense rating: DR = tier × 2 + level × tier (+ tier if glyphed)

Important: When upgrading armor with a glyph, there's a chance the glyph may be lost if the armor's current level is low. The formula is: if Random.Int(level()) > 0, the glyph is removed.

The Armor Kit is a special item that:

• Transforms regular armor into class-specific armor
• Cannot be upgraded itself (isUpgradable() returns false)
• Is already identified when found
• Is dropped by the King boss
• When used, prompts the player to select an armor to transform
• Creates a new ClassArmor instance specific to the hero's class

Class armor is a special type of armor unique to each hero class:

• Warrior: Cuirass of the Warrior
• Mage: Robe of the Mage
• Rogue: Garb of the Rogue
• Huntress: Suit of the Huntress
• Elf: Elven Armor
• Necromancer: Necromancer's Robes

Class armor provides enhanced defensive capabilities and may have special properties unique to the hero class.

The effective defense rating (DR) of armor is calculated as:

• Base DR: tier × 2
• Per Level: +tier per upgrade level
• With Glyph: +tier additional DR
• Formula: effectiveDr() = tier × 2 + level() × tier + (glyph != null ? tier : 0)

For example, a tier 3 armor at +2 with a glyph has: DR = 3×2 + 2×3 + 3 = 15

Armor can have glyphs (special enchantments) that:

• Provide additional defensive effects
• May be lost during upgrade if Random.Int(level()) > 0
• Are guaranteed to stay if the armor is being inscribed during upgrade
• Add +tier to the armor's defense rating

Armor has strength requirements based on tier:

• Formula: typicalSTR() = 7 + tier × 2
• Examples: Tier 1 = 9 STR, Tier 2 = 11 STR, Tier 3 = 13 STR
• Wearing armor without sufficient STR imposes penalties

• New armor starts unidentified
• Requires 10 hits taken while wearing to identify
• Once identified, shows the armor's level and stats
• Badges are awarded when item level is acquired

• Use Scroll of Upgrade on high-tier armor for maximum DR increase
• Be aware that glyphs may be lost during upgrades
• Save Armor Kit for the best armor you can find
• Consider strength requirements when planning armor upgrades
• Class armor is generally superior to regular armor of the same tier
