how to get lava blade in slayer battlegrounds
The Lava Blade in Slayer Battlegrounds is commonly reported to be found by going to the Ice Castle area, then defeating the Ice Admiral to get a key, and using the Library Key to access the store area; another widely shared route says to cross the river, go to the house, and drop down the hidden hole to find the blade.
Quick route
- Head to Ice Castle or the main river/house area, depending on your map progress.
- Fight the Ice Admiral and try to get the Library Key.
- Use the key to open the relevant store/library access point.
- If you are using the house route, cross the river, enter the house area, and drop into the hidden hole to reach the sword pickup.
What players are saying
A short video guide posted in 2026 describes the Ice Castle/Key route, while older Roblox guide clips describe the river-and-house hidden drop route for the Lava Blade.
“go to the house … go all the way down and until you like fall in and there you go there's gonna be a weapon right here and it is the lava blade”
Notes
- The exact spawn or unlock method may vary by update, since different guides describe different access paths.
- If one path does not work, the hidden-house route is the other most repeated method in public guides.
TL;DR: Most public guides point to either defeating the Ice Admiral for access or finding the hidden hole under the house after crossing the river.
