ACTIONS
Multiattack. The Psithalide makes two attacks, using Tri-Claw or Nerve Shock in any combination. It can replace any number of these attacks with a use of Psionic Shield.
Tri-Claw. Melee Weapon Attack: +6, reach 5 ft. Hit: 13 (2d8 + 4) piercing damage. If the target is a creature and doesn't already have a wound, it is subjected to the following effect. Constitution Saving Throw: DC 14. Failure: The target receives a wound. While wounded, the target loses 3 (1d6) hit points at the start of each of its turns. The wound closes after 1 minute, after a spell restores hit points to the target, or after the target or a creature within 5 feet of it takes an action to stanch the wound, doing so by succeeding on a DC 14 Wisdom (Medicine) check.
Nerve Shock. Melee Weapon Attack: +6, reach 5 ft. Hit: 7 (2d6) lightning damage plus 7 (2d6) psychic damage. If this attack scores a critical hit, the target becomes stunned until the end of its next turn.
Psionic Shield. The psithalide increases its AC by 3 until the start of its next turn.
BONUS ACTIONS
Aggravating Stimulus. Wisdom Saving Throw: DC 13, one creature within 30 feet of the psithalide. Failure: On its next turn, the target must use its movement to move as close as possible to the psithalide, and the target has disadvantage on attack rolls against creatures other than this psithalide carapax and can't be affected by other creatures' Aggravating Stimulus until the end of its next turn.

QUICK REFERENCE
USING MONSTER VARIANTS
Monster variants allow the GM to adjust encounters to better match the party’s strength, narrative needs, or world-building logic. A weaker variant may represent a juvenile, wounded, or lesser specimen, while a stronger variant can serve as a leader, champion, ancient creature, or apex predator.
Variants can be used to fine-tune difficulty without changing the core identity of the monster, making them ideal for scaling encounters, reinforcing hierarchy within a faction, or creating memorable boss-style enemies. You can even use the same stat block but different variants in the same encounter if you want.
Design Note. Each monster is primarily balanced around its normal version. Weaker and stronger variants are derived adjustments and may not always preserve every tactical nuance or “feel” of the original creature. GMs are encouraged to review variants carefully and adjust abilities or tactics as needed to best suit their table.
