Events are a collection of pages. Depending on which page is active, the event will appear and behave differently. To determine which page is active, a set of page conditions are used. If all page conditions are met, then that page can be activated.
By default, RPG Maker provides 5 different page conditions:

But if you wanted to have a different condition, you would need to find a way to accomplish that using only these 5 conditions. This may involve using parallel processes to check whether conditions are met, in order to turn on a switch or change a variable.
This plugin provides you with an easy way to define your own page conditions without having to come up with workarounds. If you want to check whether you have a certain weapon or armor, or whether a given combination of actors is in the party, you can directly specify this in your event.
By using custom page conditions, it improves productivity and makes it easier to manage your project. Need some more page conditions? Download the plugin and try it out!
