This is the same info in the initial post so I’m not quite sure what’s different.
The purpose of resonance is to allow you to gift the really stand out items that really hurt when they drop alone to the people you play with most frequently. It’s not for creating an open gifting environment with your friends list.
We don’t know what the minimum duration that this will be yet.
It’s a lot easier for us to reduce the duration that extend it so we will likely start with it slightly on the high side. I’m not talking anything ridiculous like 24 hours of playtime for one but it needs to be significant.
This timer is one of the key elements that keeps RMT at bay.
It should hopefully feel very natural.
It also doesn’t matter what order the item and the resonance drop in, so if you are short, just play together and you can eventually give it over.
