When you reach level 5-10, you automatically gain access to a new spell, dimension tear.
To use, you need four crystal shards, and in doing so, you can teleport to a specified location instead of player.
There's two ways this could be done.
A: New callout "List Locations", shows every location dimensional tear can go to, climbing tower, blacksmith, etc, then the player can say the target location via "Target blacksmith", "Target tower", etc.
B: You have to physically say the chunk numbers to teleport to on the map.
Optionally, if up to 4 other players hold a crystal shard near the caster, they can also be teleported to the same location, incase they want to bring someone to climbing tower.
