I think being able to create a custom battle to practice with or just have fun would be awesome. Yes, it would take a lot of time, but bring a lot of creativity to the table and bring back players or even keep players longer with unlimited possibilities.(Note: NO rewards, and I mean NO rewards should be received for completing a custom battle)
It would work like this: Name: Can type any name but still uses filtered chat to prevent vulgar names Type: Choose the model of any existing enemy for this option Rank: Choose the rank of said enemy Spells: Choose the spells which they can cast, up to 15 spells Health: How much health this enemy has Cheats: These are a bad idea as they would be impossible for players to create and take way too long for KingIsle to add Also you can bring friends to fight alongside you as well.
The scenery could be the usual tower background and it could be possible to add up to four custom enemies per fight as well as create multiple floors up to 5 for a truly unique experience.
As I said, this idea would take a VERY long time to make, but would bring so many ways for the creative people of Wizard101 to have fun.
Please, give me feedback and go as aggressive as you would like.
