Fey Dragon

A dragon who dwells too long in the Feywild may become infused by the wild magic of that place. It keeps its statistics, except as follows:

Challenge. Recalculate the creature’s challenge rating after you apply the template.

Alignment. The dragon is chaotic neutral.

Ability Score Increase. The dragon’s Wisdom increases by 4.

Skill Proficiencies. The dragon gains proficiency in Nature and Survival. If it was already proficient, the dragon’s proficiency bonus is doubled for its Intelligence (Nature) and Wisdom (Survival) checks.

Language. The dragon adds Sylvan to its languages.

Breath of Life. Any terrain affected by one of the dragon’s breath weapons is filled with the wild magic of the fey. For 1 minute, the area is affected by entangle, plant growth, or spike growth (dragon’s choice). It regains the use of spent effects after all three have been used, or after it has completed a short or long rest.

Innate Spellcasting. The dragon’s innate spellcasting ability is Wisdom. It can innately cast the following spells, requiring no material components:

• At will: faerie fire, healing word, speak with animals
• 2/day each: dispel magic, flaming sphere, pass without trace
• 1/day each: call lightning, conjure animals, conjure woodland beings, meld into stone

Iron Concentration. The dragon has advantage on Constitution saving throws to maintain concentration.

New Action: Wild Shape. The dragon can use its action to wild shape as if it were a druid of a level equal to its challenge rating.

New Legendary Action: Cast a Spell (Costs 2 Actions). The dragon innately casts a spell. If the dragon does not have legendary actions, it does not gain this legendary action.

Lair Actions and Regional Effects. The fey dragon loses any lair actions and regional effects deemed appropriate by the GM. The GM can choose any replacement actions or effects as they see fit.
