Description
A giant red dragon with a huge, gaping maw the size of a house. This dragon has dark blue eyes and large gray horns. It emanates an aura of intimidation.
Lair and Lair Actions
The Maw Dragon’s Lair
The Maw Dragon lives inside a castle on a high mountain.
In it's true stomach, a dungeon with high level enemies awaits only those worthy. It is a typical brick wall dungeon with chests and battles, but the walls, floor, and ceiling are made of slippery stomach flesh.
Throughout the slippery stomach lair complex, servants erect monuments to the dragon’s power, telling the grim story of its life, the enemies it has slain, and the nations it has conquered.
Lair Actions
Every five turns when someone is in it's true stomach, it can roll Con, if it gets a nat 20 the dragon takes a lair action to cause one of the following effects; the dragon can’t use the same effect twice in a row:
- The dragon shakes its true stomach around, causing each player to roll a Dex save, if they fail, they trip and take (1d6 + 2) damage and are stunned for one turn.
- The dragon drinks an entire lake, flooding the dungeon, dealing (1d10) water damage to anyone on or close to the ground.
- The dragon releases sticky substance into all the dungeon surfaces, all players get a -2 to dexterity and halved movement speeds for 5 turns.
- The dragon opens trap doors to the digestion stomach, if you are standing on a trap door tile, roll Dex. If failed, you will be released into the digestion stomach.
Regional Effects
The region containing a legendary red dragon’s lair is warped by the dragon’s magic, which creates one or more of the following effects:
- The dungeon inside the dragon is infested with high level dragonborn and skeletons.
- The dungeon is very slippery, so every five turns if there is no sticky substance, roll Dex with a +4. If you fail, you trip.
- Inside the digestion stomach there is one way out, the intestines. you must successfully roll 3 Dex checks to make your way through the intestines, out the behind, and down the mountain. A spell will be cast so you cannot enter the castle for three days.
The Reward
If you make it to the end of the true stomach and defeat the boss, you will be given the dragonsbane point. The dragonsbane point is a sword on a podium in the final room after the boss room. To get out, you must go through an extra line of intestines, these ones do not deal digestion damage.
Misc
If the dragon dies, the stomach collapses, killing everyone inside and teleporting the sword if it is still inside the dragon, then the dragon will be reborn. As the dragon is reborn and starts generating more servants inside it's true stomach, the sword will be teleported to the end of the new true stomach. If you die inside the digestion stomach, the dragon heals half your maximum health.
