Homebrew Fossilized Skeleton Species Details

Fossilized Skeleton Traits

Oooh, you stony, stony boy
Ability Score Increase. Your Constitution score increases by 2, and your Strength by 1.
Age. Not counting their previous lives, fossilized skeletons can be nearly any age. Skeletons don't age, and won't die of old age until the magic keeping them alive collapses or their bones give away.
Alignment. Fossilized skeletons are usually neutral, though evil or chaotic skeletons are fairly common.
Size. Fossilized skeletons range from 4 to 8 feet in height, weighing 200% of their past weight. Your size is Medium.
Speed. Your base walking speed is 25 feet, ya big stone bastard. You are unable to swim in water, as you sink. Magic is your only way to stay afloat.
Blindsight. You don't have eyeballs anymore, frankly. Instead, you now are guided by senses beyond, like detecting life faintly. You have a blindsight range of 120 feet. You are considered blind outside this range.
Undeadish Nature. You are a walking stone skeleton without flesh. Your creature type is construct instead of humanoid. As such, spells like cure wounds don't affect you, and you are immune to spells like crown of madness or dominate person because they specifically target humanoids. You are immune to poison damage, being poisoned, and diseases. You do not need to eat or breathe, and any food you do attempt to eat falls through in your jaw and into your rib cage. Rather than sleeping, you enter an inactive state for 6 hours each day. You do not dream in this state; you are fully aware of your surroundings and notice approaching enemies and other events as normal, though your blindsight is reduced to 30 ft. You have resistance to bludgeoning, piercing, and slashing from non-magical and non-adamantine attacks, and also are immune to necrotic damage, as you have already kind of "been-there and done-that." Due to being made of sedimentary rock and animated by magic, you are vulnerable to force damage from magical sources.
Magical Creation. You are held together by magic. You are incapacitated while in the area of an antimagic field. If targeted by dispel magic, you must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious until the caster's next turn.
Inexhaustible. You don't need much of a break, having no flesh. You have advantage on Constitution saving throws against exhaustion.
Magic Affinity. You, being made of magic, know more about it than others a bit. You are proficient in the Arcana skill.
Languages. You can read and write Common and one language of your choice.
