Battle of the Onyx Dragon/Session notes

### The Onyx Dragon

As the characters enter the lair, they will find the mound of coins and no dragon. If they approach the hoard, it will shift as Marwolaeth (CR 7, 127 HP, AC 19) unleashes his Ambush Drakes (CR 1/2, 22 HP, AC 13) to distract attackers while the dragon prepares his acidic breath weapon, which it uses on its first turn.

If he is defeated, Marwolaeth's body dissolves into a cloud of ash that forms itself into four Dust Mephits (CR 1/2, 19 HP, AC 12), each with its own Initiative count. On its first turn, each Mephit casts *Sleep* and then flees toward the tunnel to escape; if any attackers remain awake, each surviving Mephit will use its *Blinding Breath* on any attacker that gets within 15 feet of it. If any Dust Mephits escape, they will flee deeper into the forest and attempt to reform.

Once the Dust Mephits are either destroyed or escape: if the team rolls an Investigation check on the hoard, an 18 or higher will reveal that it is moving. If they do not roll an Investigation check and simply approach the hoard, it will begin moving and reveal itself to contain a Swarm of Hoard Scarabs (CR 2, 31 HP, AC 14).

If only one character is conscious, they may roll an Investigation check; if more than one character is conscious, one character may roll an Investigation check at advantage. Divide the roll by 4 and round up: that is the number of usable standard potions of healing (2d4+2 HP) they find among the dead bodies. On a natural 20, roll an additional d20, divide the roll by 4, and round up: that is the number of healing potions that are a potions of greater healing.
