Cave Drake

Rend. Melee attack roll: +4 to hit, reach 5 ft. Hit: 5 (1d6 + 2) Slashing damage.

Rapid blasts (Recharge 5-6). The Drake rapidly fires 1-4 balls of fire that explode on contact (no radius damage). Ranged Attack: +4 to hit, range 30/150 ft., 1 target per ball. Hit: 4 (1d8) fire damage. Each blast, when it hits the surface of an object or wall, breaks the object if it is stone or weaker. 

Delayed Blast. The Cave Drake begins to store its power. The next time it uses Rapid Blasts, each ball will be delayed and won't explode on contact with the surface of an object. They explode when someone comes within 5 feet of it, or at the start of the Cave Drake's next turn. They can also be triggered by the explosions of other balls if they are within range of their explosions (i.e. if two balls are next to each other, and someone gets too close to the first one, it explodes and triggers the second to explode). When Rapid Blasts is used this way, the details become: range 10/50, radius 10 feet. Hit: 8 (1d8 + 4) fire damage.
