Innate Spellcasting (Psionics). The shardling's innate spellcasting ability is Intelligence (spell save DC 12). The shardling can cast the following spells innately, requiring no material components:
Immutable Form. The shardling is immune to any spell or effect that would alter its form.
Sense Thoughts. The shardling senses thoughts within 120 feet of it at will. This trait otherwise works like the detect thoughts spell but isn't itself magical.
Slash. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) slashing damage.
"Shardling" is a common term for a rare kind of sentient green crystal from the Elemental Plane of Earth known more professionally as "psirock" that can absorb and redirect psionic energy. They may be small and weak alone, but in groups their psionic powers are greatly enhanced. When their physical bodies are destroyed, their minds retreat to the Plane of Earth, then form new crystals. As such, places where shardlings reform often contain many swarms of shardlings, and occasionally even great or ancient crystals.
Elemental Nature. A shardling doesn't require air, food, drink, or sleep.
