# ║ § Change Log
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ v1.0 (December 25th, 2012) - Script released.
# ║ v1.1 (February 16th, 2013) - Fixed bug with class changing.
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Summary
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ This script allows you to have equipment that levels up by gaining
# ║ experience, much like party members. As it levels up, it can get increased
# ║ stats, have new features, or change its icon, name, and price. The script
# ║ will also allow actors and classes to gain new features through leveling. In
# ║ the case of classes, it will use the associated actor's level to determine
# ║ what bonus features are granted. I may extend this into a full class system
# ║ at some point.
# ║
# ║ At the moment, equipment gains EXP as a portion of the EXP gained by actors.
# ║ I may introduce an AP-style system at some point in the future, but for now
# ║ think the current system is fine.
# ║
# ║ Note that there is currently no way for the player to check how much EXP a
# ║ weapon has or needs to level up. This will be included in a menu overhaul I
# ║ am working on, but I have no idea when that will be ready for release. I'm
# ║ not exactly focusing heavily on it at the moment.
# ║

# ║ § Required Scripts
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ SES Core v1.0 or higher
# ║ SES - Instance Items v1.0 or higher
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Known Incompatibilities
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ None.
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Installation
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ Put this script below the SES Core and Instance Items.
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Configuration
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ There is only one piece of in-script configuration - the ItemExpRate
# ║ constant in SES::LeveledEquipment. Change its value to determine how much
# ║ EXP weapons gain from battle (as a percentage of the EXP gained by the
# ║ party). By default it is set to 0.25, or 1/4 of the party's EXP.
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Tags
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ ● Weapon/Armor/Actor/Class
# ║   <Level !Level!: !Exp!>
# ║     Place this in a Notes box to set the EXP required to reach a level. It
# ║     also starts the block of added features for the level. For actors and
# ║     classes, omit the ": !Exp!" part - the format for them is just
# ║     <Level !Level!>. Make sure there is one of these for each level an item
# ║     can obtain, or else it will not know how much EXP is required for the
# ║     level, which could cause issues. Note that you do not need one per level
# ║     for actors or classes, just equipment. You can have as many or as few
# ║     of these as you would like - just don't skip levels (except level 1,
# ║     which can be skipped, as it requires 0 EXP to reach and is the default
# ║     level).
# ║     ► Replacements:
# ║       !Level! with the level you want to define.
# ║       !Exp! with the amount of EXP that the item needs to reach !Level!.
# ║
# ║   </Level !Level!>
# ║     Place this in a Notes box to finish adding features for a level. You MUST
# ║     have one of these for each level, even if nothing changes as a result of
# ║     the leveling.
# ║     ► Replacements:
# ║       !Level! with the level you are done defining.
# ║
#═╬═════════════════════════════════════════════════════════════════════════════
# ║ § Adding Level Benefits
#─╫─────────────────────────────────────────────────────────────────────────────
# ║ Add these between the tags for level definition to cause them to be added
# ║ at the proper level (henceforth called 'the new level'). Note that 'item'
# ║ simply refers to whatever object is being altered by these tags - I will
# ║ explicitly note any item-exclusive tags.
# ║
# ║   Example:
# ║     <Level 2: 20>
# ║     Atk: 4
# ║     Atk State: 1, 15
# ║     </Level 2>
# ║
# ║ The example defines level 2 as requiring 20 EXP to reach. When the item
# ║ reaches level 2, it will get +4 to its Atk stat and have a 15% chance of
# ║ instantly killing a target. For a list of tags you can use here, please see
# ║ the "Instructions for Feature Tags" text file.
