This plugin is amazing. It's really lightweight and adds a lot to your server.

With this plugin, there are close to 40 events that you can have run that provide players with bonus exp. This is additive to the rates you have set in Skill Tree.

I have found that setting an event to last for 10 minutes gives players enough time and chance to take part in this. Personally, I have it set to equal chance that an event triggers so that it's totally random. I have an event trigger every 15 minutes, so 4 per hour, with 40 minutes of the hour having one active. 

With this, I've noticed that my players have started doing activities they don't normally take part in. Players have started learning how to farm for the events that give bonus exp to harvesting. I've noticed players skin animals where they'd just leave them. Honestly, do not be fooled, this plugin brings and adds a lot to Skill Tree & your server.

You won't regret buying this plugin!

It is a really great plugin! It encourages players to complete tasks that they otherwise wouldn't do. The config offers many options for customization. A well written plugin, nice work.
