Spelleater (Recharge 4-6). The woe beast gazes in a 90-foot cone. Each spellcasting creature within the cone must make a DC 18 saving throw in their primary spellcasting ability. Creatures with more than one ability score governing their spellcasting use the lowest relevant ability score. On a failure, the target loses a spell slot of 1d10 - 1 spell level. If no spell slot is available of the designated level, the target loses the highest spell slot of a lower level that they still have available. The woebeast gains temporary hit points equal to the total number of spell-levels consumed. These temporary hit points do not stack, so subsequent use of the Spelleater ability replaces previous temporary hit points. On a successful save, a target is unaffected.

Bonus Actions

When a woebeast successfully lands a Force Slam attack on its turn, it may choose to use a bonus action to move up to half its movement without incurring an attack of opportunity.

Legendary Actions

The woebeast has three legendary actions per round, which it can only use at the end of another creature's turn.

Misty Step. The woebeast may cast the misty step spell without needing components.

Invisibility. The woebeast may become invisible. This invisibility persists until it makes an attack. It cannot use its Spelleater or Woeful Presence abilities while invisible and cannot drop the invisibility as any action or free action. The invisibility is only revoked if it makes an attack.

Melee Attack. Theh woebeast may make a single attack with either a Force Slam or a Bludgeoning Tongue Bite.

Lair Actions

On initiative count 20 (losing initiative ties), the woebeast takes a lair action to cause one of the following effects; the woebeast can’t use the same effect two rounds in a row:

• Each creature of the woebeast's choice within 30 feet of the woebeast must succeed on a DC 14 Wisdom saving throw or suffer horrible intrusive thoughts of torture, pain, misery, death, disease, etc., to themselves or their loved ones. Any creature so affected has disadvantage on all attacks and ability checks until initiative count 20 of the next round.
• Up to three creatures the woebeast can see must succeed on a DC 14 Constitution saving throw or suffer 3 (1d6) psychic damage as pain racks their body. The woebeast heals for a number of points equal to the damage the target creatures take.
• Up to three creatures the woebeast can see must succeed on a DC 14 Wisdom saving throw or suffer the blinded until initiative count 20 of the next round.
• A single creature the woebeast can see must succeed on a DC 14 Constitution saving throw or have its vocal cords seize up. For the next six seconds, it makes an incomprehensible, guttural moan, and it cannot speak or cast spells with verbal components until initiative count of 20 of the next round.

A woebeast's lair is scaled appropriately to the huge creature's size. It is a miserable den of filth, disease, and decay. Beasts and most monsters avoid the region within a mile of a woebeast's lair. Any creature that enters a woebeast's lair must make a DC 12 Constitution saving throw or contract a disease of the DM's choosing. The character will be unaware this occurred until symptoms manifest 1d4 + 2 days later.
