Shardmind

Age Shardminds awaken at full size and are treated as adults from their first day. Unadventurous shardminds can live to be about 130 before their psionic imprint starts to fade.   Alignment Shardminds tend towards lawful as they learn about the world around them, but lean towards chaos later in life.     Crystalline Body Your unique body material changes the way you react to physical trauma, when compared to more conventional races. You gain resistance to slashing damage from non-magical weapons. You gain vulnerability to bludgeoning damage.   Psionic Mind Your mind exists solely due to the psionic power of those that awoke your clutch. You learn the Message cantrip. When you reach 3rd level, you can cast the Mind Spike spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the Resonant Imbalance (Book of Lost Spells) spell once with this trait and regain the ability to do so when you finish a long rest. Intelligence is your spellcasting ability for these spells.   Mental Link Whenever you cause a creature to take psychic damage, you gain temporary hit points equal to your proficiency bonus + your intelligence modifier.
