Medieval Master
The Medieval Master is a powerful tool in order to help admins and moderators to maintain their servers and singleplayer worlds. You can open the screen by pressing Alt + F10.
Creative Mode Tools
Activating creative mode tools in a multiplayer game will give you all the powers as if you were in a creative single player game, so use them wisely.
Building
Just like in creative mode, you will no longer need resources to place or build large grid blocks. Right-click will remove a block instantly, even if you have no hammer equipped. You can also use CTRL + C to copy, CTRL + X to cut and CTRL + V to paste a grid from or to your clipboard
Spectator & Fast Travel
Use F6 - F9 to enter the spectator cameras. You can teleport your character with CTRL + Space while in free spectator camera (F8).
If you want to teleport to specific coordinates on the map you have to use the fast travel feature. If there are fast travel limitations and a cooldown enabled in the world settings, you can use the creative mode tools to override at least the cooldown timer (if there is no timer active yet) and travel multiple steps at once.
Item Spawning
Press Shift + F10 to open the spawn menu. You can browse through resources, consumables, small grid blocks, tools and schematics. Just set the desired amount and spawn them right in front of you by clicking Spawn. If you want them to spawn directly into your inventory, double-click the item or click on the Add to inventory-button
