Dynamic Leads is a building tool made with Skript that enables builders to place leads and lead knots anywhere in the world.

 

This allows for some unique designs and detail to builds, as otherwise leads and knots can only naturally exist in the world while being tethered between a mob and a fence.

 

Additionally, this system allows for leads to be any length, as typically they would break if extended past 10 blocks. Knots can also be anywhere without despawning.​
