A choice between two:
Charming Monster. You are incredibly alluring to other creatures of the opposite gender. When conversing with a humanoid of the opposite gender you gain advantage when trying to persuade them to do something.
Speakers. You are one of Spindallas speakers, you can communicate with spiders using the name of your queen to pacify or enlist them. The spiders can communicate simple ideas back to you. If accompanied by several spiders you may spend 10 minutes to construct a web matrix that spans up to 100ft. When in the web matrix your passive perception is increased by 5.
The children of Spindalla are creatures that tend to live in incredibly large broods or all alone. However, all follow the orders of their queen. Many fear the stronger of the great brood and the mother of spiders herself, some of these wish to be free of the queen entirely, but know that if they flee they will incur her wrath. The marital status of the species differs for each individual. Some like to surround themselves with as many mates as possible, others only love one. Some care little for the race and gender of their mates and for others it is important. Consider this when making your spider person.
