Currently the way that spirit chain works, the link is so easily broken because player either overestimate it’s range, doesn’t know what it does, or just selfishly doesn’t care for it, jeopardizing a buff that can benefit the entire team; especially when life line is also active.
So what I suggest is at C3 linker, give it a toggelable attribute that when active turns the spiritual chain into a buff on the linker. Where any party member who is close to the linker while the spiritual chain buff is active will be connected to the linker and any other party member close to the linker. And when a party member strays too far, he/she gets disconnected from the link but can reconnect once he/she is in appropriate range of the linker once again.
Thoughts?
