Portals are most useful when they reduce repeated travel without making the network hard to understand. Consistent naming and clear roles matter more than building many portals quickly.
Give each portal a clear purpose
A portal should connect to a base, resource area or exploration region you expect to revisit.
Use a consistent naming system
Predictable names reduce mistakes and make temporary connections easier to manage.
Place portals where they shorten real travel
A portal is most valuable when it removes a route you would otherwise repeat often.
Keep recovery in mind
A portal network can also act as insurance after death or a failed expedition.
