Jaculus are small (up to 24”), green, arboreal snakes with narrow, retractable sails on either side of the front half of their body. They leap on targets from tree branches, by means of coiled, spring like tails suddenly straightening, propelling them forward with their sails gliding to them to their targets in a single devastating attack. In this first attack, unless their victims are already alert to the possibility of jaculus being present, they surprise their targets on a roll of 1-4 on 1d6.
Their initial devastating attack is their sole means of taking prey. They will attack almost any target, anything up to the size of a human, and if they fail to kill that target they will immediately try to retreat and climb back into a tree to escape
