As Doo linked the thread that already exists, allow me to link my response, which is still relevant for this particular issue (in the sense that there are other high priority tasks at hand.) https://royals.ms/forum/threads/automatic-rewarp-for-boss-run-dc.115039/page-4#post-1198707
I've read the thread, and i really like the idea of sending characters to a limbo-esque kind of map with a rewarp NPC with the choice to rewarp back into the boss map or return to town. Obviously there are concerns of it being abusable like disconnecting on purpose to avoid death, or buyers disconnecting and only reconnecting 30 minutes later when the boss are dying, etc. I think those could be mitigated to a certain degree if the rewarp npc allowed rewarping only once per boss entry instance and an automated sendback to town if the rewarp npc isn't used within .. let's say 5 minutes from time of DC? It serves as a deterrence to potential abusers because it'd be like "hey i've only got one rewarp available, do i really wanna use this rewarp to avoid this death? what if i really do DC later on"
