Your Erlking powers allow you to expel a 30ft cone of pure, thunderous mana, dealing force and thunder damage split evenly.

When you make the attack action, you may replace one of your attacks to expel your Breath Weapon. Each creature in the area of effect must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your Proficiency Bonus). A target creature takes 2d8 force and thunder damage on a failed save, or half as much damage on a successful one. This damage increases by 1d8 when you reach character levels 5 (3d8), 11 (4d8), and 17 (5d8).

Per Long Rest, you can use this feature up to {{proficiency#unsigned}} times

When defeating a creature, you may eat it to gain its power. When doing so, you gain some of its abilities through a feat. This may be done to one creature per long rest.

Though the CR and type of creature matters. If you eat a creature that is CR one and below, it does nothing. Additionally eating creatures of low CRs might not give you anything either, this still wastes your one Cannibal use. Additionally if a creature is the same kind of one you've already eaten, for example two young black dragons, you gain nothing. Only when a creature has an unique ability that is the same type do you get it.

At the start of a campaign you gain 1 Cannibal feat of a creature below CR 3.

You have Resistance to Force damage at level 1, you also gain resistance to Thunder damage at level 5

A life spent in shadow has made you grow accustomed to the gloom. You can see in Dim Light within 60 feet of you as if it were Bright Light, and in Darkness within 60 feet of you as if it were Dim Light. You can’t discern color in Darkness, only shades of gray.

Your battle cry can cause even the most formidable foes to quail before you. As a Bonus Action, you emit a roar, shout, or other loud vocal outburst. Each creature of your choice within 10 feet of you that can hear you must succeed on a Wisdom saving throw (DC = 8 + your Proficiency Bonus + your Constitution modifier) or have the Frightened condition until the end of your next turn. You regain the use of this feature when you finish a Long Rest.

Whether carrying well-earned loot or the body of a fallen companion, you shoulder that load with ease. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

Others have learned to fear you—and for good reason. You have proficiency in the Intimidation skill.

You have proficiency in the Athletics skill.

As a bonus action, or automatically when you drop below half HP you may take 2d6 damage and unfurl your draconic wing. Your wing is unfurled for 10 minutes, or you may use a bonus action to put it back within your body. During this time you have the following features;

• You get a flight speed equal to your walking speed
• You may dash as a bonus action
• You are immune to the Grappled condition, and moving a creature you have grappled doesn't cost extra movement
• When flying in a straight line, each 5ft of movement grants you an extra d4 of damage on your next Melee attack.
• When midair and using Shove, it automatically shoves the person 10ft- it does not do the same for making a creature prone.

When entering this state, you must do a DC 12 Wisdom saving throw; on failure, you turn savage and attack the nearest creature to you as a reaction. You repeat this save at the start of your next turn. If you fail, you must use all of your attack on the closest creature to you. On success, nothing happens.

You may use this feature once per long rest; you may take an exhaustion point to reuse the feature.
