This material adds additional prehensile grasping limbs to a character, giving them more usable "hands" than is anticipated by the core rules. DMs and players should be aware that this can allow characters to do things which are normally impossible, such as: dual-wielding two-handed weapons; holding four weapons at once; having a free hand to load ammunition while holding two hand crossbows; the option to hold a shield, sword, and bow or casting focus simultaneously; the ability to grapple with a character and still have free hands to hold weapons to attack them with; the ability to be climb and defend oneself effectively at the same time; and much more. Be careful about who is allowed to use this material, as immature players will likely abuse this to break combat in unanticipated ways. As should be standard, such situations should be dealt with outside-of-game through open communication, but it is often best to avoid the situation in the first place. New players often have difficulties visualizing themselves as another person, let alone another creature with completely alien/foreign anatomy. As such, if a new player is allowed to use this material, they may need some degree of guidance to remember that their character has more than two hands, though it should only take a few sessions to really drive the point home.
