boozeBooze is a discord bot which has a lot of moderation and is on 24/7 (may have some down time). Also the bot has many other features too.
A unique bot you could use for say moderation or economy purposes. Also the bot has a music feature which allows you to play music in a vc either by yourself on with someone.
One feature I really like is the economy feature like I mentioned. You can have your own balance and try to get more money to buy things. This can be useful if you just want to have some fun in your server.
note: the economy system is in beta (may reset your money everyday) note: if the music stops working or a command doesn't work contact me on discord mp5#1337
