A new outcome: random exp bottles will appear around you.
Now you can enable/disable the HeadMode info in the console (the enable and disable message).
Now you can create your own outcomes. In order to create new outcomes, you need to change the 'Main-probability' value in the 'custom_outcomes.yml' and the same in the 'outcomes_probability.yml' file to the probability that you want. Depending on these values, it will occur custom events or non-custom ones.
Then, you can use the "/alb menu" command to use the GUI menu or you can edit the 'custom_outcomes.yml' file directly. If you want more information about creating new outcomes, you can read the tutorial "How to create new outcomes".
