Hi everyone!

This plugin adds fields into your game, a way to model the environment of your game in battles.

Key Features:

• Fields allow fine-grained control over the behaviour of each individual skill and item while they are active!
• Easily adjust base parameters such as damage, speed, accuracy, or MP cost!
• Fields can be transformed into other fields by use of skills and items, making battles more dynamic AND strategic at the same time! (think e.g. a lake getting frozen by an ice spell)
• Set custom battle scene backgrounds for fields!
• Override skill elements, or, using Yanfly's Element Core (see here), add multiple new elements!
• Using Yanfly's Auto Passive States (see here), easily add passive states while in a field!
• If you're proficient with JavaScript, you can implement complex field effects using special evals at various different battle phases!
• A plug-and-play extension plugin for displaying each field's effects to the player!
• And more!
