Random Event, as the name suggests, is an event that can be triggered randomly during gameplay if certain criteria is met.
There are two types of Random Event:
- Explore random event: When you perform a certain action in a port - usually a explore action - you trigger a random event, chosen randomly from a pool of events available to that port.
- Zee random event: These can happen anytime while you are at zee if you meet the requirements for it to trigger.
