Interesting that another bug/glitch/skip was found, nicely done.
It would be multilog, but the meta for Tutorial Island has already evolved into needing multilog strats to be efficient, so that's acceptable.
The only problem in the foreseeable future is if they were to patch it out. I'm not quite sure what we would do with your run (assuming it WR's again). But for the time being, I would say go for it, but that's just my opinion.
Pretty cool stuff, I think it should totally be allowed. Makes me wonder what else might be manipulable too. For example can you drop items for others to pickup on Tutorial Island? Will have to do some testing soon.
no you cannot pick up others drops on tutorial island. however you can pick up bones that others did not pick up off of rats they killed. but thats the only somewhat way around it for anything on the island.
