Elder Black Dragon
Huge natural magical beast (aquatic, dragon)
Level 18 Solo Lurker XP 10000

Traits

Acidic Blood (acid)

Whenever the dragon takes damage while it is bloodied, each creature adjacent to it takes 10 acid damage.

Aquatic

The dragon can breathe underwater. In aquatic combat, it gains a +2 bonus to attack rolls against nonaquatic creatures.

Instinctive Devouring

On an initiative of 10 + its initiative check, the dragon can use a free action to charge or to use bite. If the dragon cannot use a free action to make this attack due to a dominating or stunning effect, then that effect ends instead of the dragon making the attack.

Action Recovery

Whenever the dragon ends its turn, any dazing, stunning, or dominating effect on it ends.
