Bola

The Bola is a primitive throwing weapon — typically made of weights attached to ropes — used to immobilize small and medium-sized creatures. When thrown, it wraps around a target’s legs or body upon impact, ensnaring them.

The Bola immobilizes creatures for 20 seconds, keeping them rooted in place.

Big(like bear and moose), mechanical and corrupted creatures cannot be immobilized!

Bola also cannot be recovered when it hits a creature that can be immobilized!
If Bola hits ground, it will break, leading to 2-4 ropes appearing in place of the hit. If Bola hits a creature that cannot be immobilized, 1-2 ropes will appear in place of the hit instead.

Immobilized creatures cannot be mounted, and players caught in a Bola cannot mount any creatures.
Hitting the creature a player is riding, or the player themselves, with Bola will dismount the rider.

If player becomes entangled in a Bola, they can select an empty Hotbar slot and press the Left Mouse Button to free themselves.
If player wants to release a creature caught in a Bola, they can attack it with empty Hotbar slot while Sneaking to remove the bola.

As of v1.1.0, Bolaed entities can be tied with rope.
Generation of creature gets set to minimum of 2 for it to work, but resets to original value when Bola effect expires or rope gets attached.

As generation is set to minimum of 2, not all creatures can be ropetieable!

If entity gets tied with rope, duration of immobilized state becomes 80 seconds. That allows players to drag creatures with ropes.

As of v1.4.0, baby creatures or creatures that have trappable attribute and non-zero trapping chance, and catched in Bola, can be put into reed chest. Not all creatures can fit into reed chest.

Bola effects are configurable (see the spoiler below).
