Spikes were two-pronged impaling devices with a single-hand handle developed by the Indian Brotherhood of Assassins. When used to pin a target to the ground, the spike itself would emit a substance that was known to provoke terrifying hallucinations, causing the target's fear to spread to enemies around him or her. The target was likely to scream in fear and pain, both causing panic among those who witnessed the impalement and drawing the attention of additional opposition from further away.

After learning from the Indian Assassins, Evie Frye utilized these spikes in her own missions, including her hunt for Jack the Ripper, who used the weapons as well.
