Description
Throwing a spear through a Batfly already on another spear causes the game to think the Batfly is on both spears, creating a link between them. Any amount of spears can be linked in this way.
Once Spears are linked, they remain linked until the Batfly is destroyed or removed from a Spear. Destroying a Spear - such as by dropping it into the deathplane - does not destroy Spears linked to it. Linked spears can be thrown at other creatures to create an object link between them and the Batspear.
If a linked Spear is pinned in geometry, it will pinwarp to its lodged position in the new room after being warped through a pipe. However, it will not function as a pole in the new room until batspear realization is performed.
