Adaptive Form. At the end of its turn, the guardian rolls a d4 to determine its next form, which it assumes at the start of its next turn. The guardian gains a damage vulnerability tied to its upcoming form until the transformation occurs.

• Radiant Storm: Creatures within 15 feet of the guardian must succeed on a DC 18 Constitution saving throw or take 21 (6d6) radiant damage and be blinded until the end of their next turn.
• Crystalline Knight: The guardian’s AC increases to 22, and it gains 25 temporary hit points. Its melee attacks deal an additional 10 (3d6) slashing damage.
• Swarm of Butterflies: The guardian becomes incorporeal and can pass through other creatures and objects. It can occupy another creature's space and automatically deals 14 (4d6) radiant damage at the start of that creature’s turn.
• Verdant Bloom: The guardian releases a burst of magical pollen in a 20-foot radius. Each creature in the area must succeed on a DC 18 Wisdom saving throw or be charmed until the end of the guardian’s next turn. Charmed creatures cannot willingly move or attack.

Illusory Doubles. When the guardian is targeted by an attack, roll a d6. On a 4 or higher, the attack targets an illusory duplicate instead of the guardian. The duplicate is destroyed after the attack resolves. The guardian can have up to 3 duplicates at a time.

Magic Resistance. The guardian has advantage on saving throws against spells and other magical effects.

Future Glimpse. A creature that uses an action to study the guardian or gazes into the Reflecting Pools can make a DC 18 Insight check. On a success, they choose one of the following boons:

1. Learn the guardian’s next form and its associated damage vulnerability.
2. Ignore the effects of Illusory Doubles for themselves and their allies until the end of the creature’s next turn.
