Yeah I've never heard of that so it's probably console only. If that's the case it likely won't be added as a category.
As of now mithril is simply not required for any category(check under game rules).
Anyway, getting mithril kinda sucks, maybe 100% will require it in the future but that's not my decision to make.
Update on timers:
Using a timer is no longer required on any run, I now use a frame timer instead.
You can find the tool here if you would like the time your runs: https://slashinfty.github.io/yt-frame-timer/
Sorry i don't get notifications from this forum, but what would be the goal for speedrunning the spinners level?
If you go to game rules you can see whitelisted mods, which you are allowed to use.
Whitelisted mods: Calamity Mod Music, Recipe Browser, Boss Checklist, Yet Another Boss Health Bar, What Mod Is This From
It may be allowed to use purely cosmetic mods and such, but recommended to stick to the whitelist.
I think the best option would be to simply change the "no endstone" categories to "no endstone/mithril"
Like every category except for the races has to be on a new profile. But you don't have to buy a new account, you should be able to make a new skyblock profile via the nametag in the skyblock menu
You may submit under 1.3.5, assuming that's what version those consoles are on.
thats pretty slow man
The run uses three seeds but the main seed used in the run is: 1.4.1.796315845
We'll have to wait on Max for the other two seeds
The streamable link syncs them all at "get ready" so I suppose that should clear up your issue with the "good start". Anyway, the in game time seems to be inaccurate for some reason, but I'm not sure why, if you look at the real time, the 11 second runs are clearly considerably longer than the timer shows.
After reviewing the recent 11 second runs, it has come to my attention that the in game time is wildly inaccurate. Due to this, top level runs will now be timed with real time.
