====== Armor Upgrades ======

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

==== Upgrade Methods ====

===== Scroll of Upgrade =====
The [[en:rpd:scroll_of_upgrade_item|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.

===== Armor Kit =====
The [[en:rpd:armor_kit_item|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 [[en:rpd:king_mob|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 System ====
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.

==== Armor Defense Calculation ====
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

==== Glyph Interactions ====
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

==== Strength Requirements ====
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

==== Identification Mechanics ====
  * 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

==== Strategy ====
  * 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
