Killer WhaleHuge beast
Echolocation. The whale can’t use its blindsight while deafened.
Hold Breath. The whale can hold its breath for 30 minutes
Keen Hearing. The whale has advantage on Perception checks that rely on hearing.
Maneuvers. The killer whale uses maneuvers (maneuver save DC 14). It has 9 stamina dice which are d8s, a dice limit of 1, regains all expended stamina dice when it finishes a long rest, and regains half its total stamina dice (rounded up) when it finishes a short rest. It knows the following maneuvers:
Bite. Melee Weapon Attack: +6 to hit, reach 1 m. Hit: 21 (5d6 + 4) piercing damage.
As an action, you can make a melee weapon attack against a creature after you move at least 4 meters straight toward it. Add the stamina die to the attack’s damage (add half if you miss by 4 or less). On a hit, if the creature is your size or smaller, the creature must succeed on a Reflex saving throw or you can push it up to 2 meters away from you and knock it prone.
You can increase the damage, target a creature of a larger size, and push the creature an additional 1 meter for each additional stamina die expended.
As an action, you roar, rear up, flex your wings, or do another similar movement that frightens creatures. Each creature of your choice in a sphere around you must succeed on a Will saving throw or become frightened of you for the duration. A construct or an undead is immune to this effect.
While frightened by this maneuver, a creature must move at least half its speed away from you by the safest available route on each of its turns, unless there is nowhere to move. If the creature ends its turn in a location where it doesn’t have line of sight to you, the creature can make a Will saving throw.
On a successful save, the effect ends for that creature.
If a creature’s saving throw is successful or the effect ends for it, the creature is immune to your Fearsome Beast for the next 24 hours.
As an action, you can use the Dash action. If you move at least 4 meters straight toward a creature, you can make a melee weapon attack against it. Add the stamina die to the attack’s damage (add half if you miss by 4 or less).
You can increase the damage for each additional stamina die expended.
