Maybe instead of 1-3 minutes, how about 40-60 seconds after death?
Or just have no respawn at all. Maybe a message that says "Permanent Death in... [Time]"
So I'll have to rejoin every time I get hit or fail?
Or you could just respawn as normal and then if someone revives you it will say "Joe has revived you do you accept"And then you'd type /no or /yes
