Kinda got an idea here. So, Let’s say, you want a bunch of people to a location? Maybe for a new sorcery end game spell. Allow sorcery to place a summon spot in two locations.
What would be the negatives? The portal degrades over time. (Instability, meaning health loss through travel, and or death if it becomes too unstable over time)
The benefits? if you’re trying to summon a far away clan member or person on the server to your location. Portal would be public too. So if you see a open portal. Do you risk going through it?
