This variation of the Hookshoot can be obtained from killing the spider boss. It is the fastest and longest range grappling device in introduced by the Better Dungeons mod. Instead of launching a hook, it launches a spider web-like attachment.
Instead of being automatic like the HookShoot and LongShoot, the Spider hook will only reel you towards a hooked object when you hold shift, similiar to the ManualShoot. Also like theManualShoot, holding space will reel out the line.
As long as it correctly hooked on to something, the user will take zero damage when using the Spider Hook while falling. It can also hook onto a mob and pull it towards you, which can be useful in pulling mobs off walls.
To use the Spider Hook, point at a surface and right-click. Press shift to reel in, and right-click again to release.
