Dyrrn

Lair Actions

Source: Eberron: Rising from the Last War

While within the Palace of Sinew, Dyrrn can invoke the ambient magic to take lair actions. On initiative count 20 (losing initiative ties), Dyrrn can take a lair action to cause one of the following effects; it can’t use the same effect two rounds in a row:

• Dyrrn uses its Corruption action.
• A 30-foot-square area of ground within 120 feet of Dyrrn sprouts tentacles until initiative count 20 on the next round. Any creature that starts or ends its turn in the area must succeed on a DC 23 Strength saving throw or be restrained. A creature can escape the tentacles with a successful DC 23 Strength (Athletics) or Dexterity (Acrobatics) check as an action.
• Each creature of Dyrrn’s choice that it can see within 120 feet of it must succeed on a DC 23 Wisdom saving throw or take dice:4d12|noform|noparens|avg|text(26) (4d12) psychic damage. Unless the target has immunity to psychic damage, its Intelligence score is reduced by dice:1d4|noform|noparens|avg (1d4) each time it fails the saving throw for this lair action. The target dies if its Intelligence score is reduced to 0. The reduction lasts until the target finishes a short or long rest.

Regional Effects

Source: Eberron: Rising from the Last War

A region containing a passage to Dyrrn’s lair is warped in one or more of these ways:

• Plants and animals raised within 2 mile of the passage have twisted, aberrant forms. Use the Daelkyr Modifications table for inspiration.
• Creatures within 1 mile of the passage frequently feel as if something is crawling under their skin.
• If a humanoid spends at least 1 hour within 1 mile of the passage, that creature must succeed on a DC 22 Wisdom saving throw or descend into a type of madness (see “Madness of Dyrrn” below). A creature that succeeds on this saving throw can’t be affected by this regional effect again for 24 hours.

If Dyrrn dies, these effects fade away after dice:1d10|noform|noparens|avg (1d10) days.

Madness of Dyrrn

If a creature goes mad in Dyrrn’s lair or while it can see the daelkyr, it gains a form of indefinite madness. Roll on the Madness of Dyrrn table to determine the nature of this madness, which takes the form of a character flaw that lasts until cured. Chapter 8 of the “Dungeon Master’s Guide” has more information on madness.
