Unicorn

Regional Effects

Source: Monster Manual (2024)

The region containing a unicorn’s lair is changed by its presence, creating the following effects:

• Obscuring Foliage. The unicorn and its allies have Advantage on Dexterity (Stealth) checks while within 1 mile of the lair.
• Positive Energy. Whenever a creature within 1 mile of the lair regains Hit Points from a spell, it regains the maximum number of Hit Points possible. Additionally, the effects of curses are suppressed within 1 mile of the lair.

If the unicorn dies or moves its lair elsewhere, these effects end immediately.
