Legendary Actions

Lair Actions

When fighting inside it~ lair, a beholder can invoke the ambient magic to take lair actions. On initiative count 20 (losing initiative ties), the beholder can take one lair action to cause one of the following effects:
• A 50-foot square area of ground within 120 feet of the beholder becomes slimy; that area is difficult terrain until initiative count 20 on the next round.
• Walls within 120 feet of the beholder sprout grasping appendages until initiative count 20 on the round after next. Each creature of the beholder's choice that starts its turn within 10 feet of such a wall must succeed on a DC 15 Dexterity saving throw or be grappled. Escaping requires a successful DC 15 Strength (Athletics) or Dexterity (Acrobatics) check.
• An eye opens on a solid surface within 60 feet of the beholder. One random eye ray of the beholder shoots from that eye at a target of the beholder's choice that it can see. The eye then closes and disappears.
The beholder can't repeat an effect until they have all been used, and it can't use the same effect two rounds in a row.

A beholder's central lair is typically a large, spacious cavern with high ceilings, where it can attack without fear of closing to melee range. A beholder encountered in its lair has a challenge rating of 14.

Regional Effects

·A region containing a beholder's lair is warped by the creature's'unnatural presence, which creates one or more of the following effects:   • Creatures within 1 mile of the beholder's lair some- times feel as if they're being watched when they aren't.   • When the beholder sleeps, minor warps in reality occur within 1 mi1e of its lair and then vanish 24 hours later. Marks on cave walls might change subtly, an eerie trinket might appear where none existed before, harmless slime might coat a statue, and so on. These effects apply only to natural surfaces and to nonmagical objects that aren't on anyone's person. If the beholder dies, these effects fade over the course of 1d10 days.

One glance at a beholder is enough to assess its foul and otherworldly nature. Aggressive, hateful, and greedy, these aberrations dismiss all other creatures as lesser beings, toying with them or destroying them as they choose. A beholder's spheroid body levitates at all times, and its great bulging eye sits above a wide, toothy maw, while the smaller eyestalks that crown its body twist and turn to keep its foes in sight. When a beholder sleeps, it closes its central eye but leaves its smaller eyes open and alert.
