Special Traits

Reactive Instability (1/Turn). If the shardling echo is hit by a melee attack, roll a d6: On a 1–2: It detonates violently and is destroyed. Each creature within 5 feet must succeed on a DC 12 Constitution save or take 7 (2d6) necrotic damage. On a 3–6: It phase-shifts reflexively, teleporting up to 60 feet to an unoccupied space it can see.

Interference Field. The shardling emits a warped magical aura in a 10-foot radius. While within this area, enemies have disadvantage on concentration checks and can’t take reactions triggered by spellcasting. This field fades when the echo is destroyed.

Shardstatic Pulse (Recharge 5–6). The echo emits a low, stuttering frequency of shard energy. Each creature within 15 feet must make a DC 12 Wisdom saving throw or have disadvantage on their next attack roll or ability check before the end of their next turn.

Splintered Form. The shardling echo is considered to be in partial phase. While motionless, it has resistance to all damage, but loses this resistance if it moves or takes an action.

Fragile Construct. The echo automatically fails Constitution saving throws and is destroyed if reduced to 0 hit points or at the end of 10 rounds.

Actions

Shard Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage and the target must succeed on a DC 10 Constitution saving throw or suffer a minor shard wound—disadvantage on the next Wisdom (Perception) check they make before the end of their turn.

Echo Flicker (1/Day). The echo splits into two briefly, creating a visual illusion of itself. Until the start of its next turn, the next attack against it has disadvantage, and it leaves behind a static afterimage that grants half cover to the nearest creature within 5 feet of the echo. The illusion lasts until the start of the shardling's next turn or until it is hit.
