Tracker/Timer Website for the Hypixel Skyblock Magma Boss
You can get the spawn info used by the website and various mods by querying https://hypixel-api.inventivetalent.org/api/skyblock/bosstimer/magma/estimatedSpawn, which will return an estimate field which is the UNIX timestamp of the next estimate spawn.
For more info on the other info returned by the API or more advanced usage, please join my discord server
