Saun deDefri +1 Aberration Ruin Distance Returning Throwing Axe
deDefri was the founder of a githyanki martial tradition devoted to hunting down illithid. deDefri Stalkers are trained in a wide variety of weapons and defensive mental techniques. The saun is one of these weapons, a heavy version of the shuriken that can be held and used in close combat. It counts as a Light Martial Weapon, and uses the same stats as a throwing axe.
A Stalker who graduates to the 2nd Sorcerous Circle within the tradition is given one of these devices with the enchantments listed above. These weapons are important tools in the Stalkers' tactics, used to disable mind flayers as early in the fight as possible and provide the gith with the upper hand.
