Legendary Realms
Quickstart
- Open the Creative inventory’s Tools tab and take the Structure Wand.
- Right-click to throw it toward a clear building site. When it hits a block or entity, it places the default structure facing the direction you were looking when you threw it. Leave plenty of room.
- To browse and place the available template directly, use
/structure list, then/structure build legendary_realms. You can add a target size from 16 to 256; the structure will scale down to fit, but won’t scale above its full size.
Overview
Legendary Realms currently provides a structure you can place on demand, rather than an evidenced system of naturally spawning adventures. The loaded template is named legendary_realms.
How To Use
- The Structure Wand is a single-item tool found in the Creative Tools tab. It has a 60-tick cooldown.
/structure listshows the available structure names and their dimensions./structure build <name>places a structure at your position at full size, oriented to your horizontal facing./structure build <name> <size>sets a target for its longest dimension. The size argument accepts 16–256; values above the template’s full size do not enlarge it.
Crafting And Obtaining
There is no recipe listed for the Structure Wand. Obtain it from the Creative inventory. Use the structure commands to place a template by name.
What It Adds
- A Structure Wand that throws a projectile to trigger placement on impact.
- A named structure template that can be built with the wand or the structure commands.
Natural generation, dimension-specific structures, loot, and creature encounters are not documented as available features.
