Base Class: Druid
With Circle of the Plagues, you can easily revive your downed allies from any distance or sap the health of enemies to add to your pool of energy, which is channeled through The Raven's Mask, to use your abilities.
Raven's Mask
Beginning at the 2nd level, you may summon the Raven's Mask, which looks identical to a plague doctor's mask, letting you channel certain abilities through it.
- When summoned, you choose whether to gain an aura. This aura will give you advantage on intimidation or persuasion checks, you choose which one. This effect ends whenever the mask is removed.
- While the mask is active, you gain advantage on saving throws against poison and any gaseous effect.
- These effects do not apply while in wildshape, unless it is into a Raven.
Whether the mask is summoned or not, it holds Plague dice. One Plague dice is equal to 1d8, and you can hold as many equal to your druid level. When taking a long rest, you regain all of your Plague dice.
Whenever a creature, drops to 0 hit points within 60ft of you you gain one Plague dice. This can be any creature, including your party members.
This mask also allows you to wildshape into a raven at any level.
Raven's Sovereignty over Life
Starting at the 2nd level, if a creature nearby is reduced to 0 hit points, as a reaction, you can roll any number of Plague dice and heal the target that amount.
Alternatively, if wildshaped into a Raven, you may attack with your Plague dice, causing your eyes to glow a mystical green, launching wispy, ghostlike projectiles out of your eyes, dealing damage equal to the amount rolled by the Plague dice. You shoot one projectile per Plague die rolled.
You also gain the ability to wildshape into a Raven at any level.
Mask of the Plague Sender
Starting at the third level, as an action, while your mask is on and you are looking at an enemy, you may cause your eyes to glow a violent green, and they must make a DC 18 Intelligence saving throw or become poisoned, paralyzed, or blinded, your choice of the three. On a successful save, damage equal to one Plague die.
This costs one plague die to use and cannot be used while in wildshape.
Speaker of the Ravens
Starting at the 6th level, you can communicate perfectly with crows and ravens and you both understand what the other is saying, and raven will do as you ask them to, as long as the task isn't too large.
Additionally, while in Raven form, you can replace it's stats with your own, including saving throws, and ability checks, and you roll all charisma and intelligence checks with advantage, and dexterity saving throws with advantage.
While in Raven form, if you are perched on an ally, all attacks against you roll with disadvantage, and enemies cannot attack you on the first round of an encounter.
You may also fluently speak any know language when in Raven form.
Ward of Ravens
Starting at the 10th level, when healing a creature using Raven's Sovereignty over Life, you can choose to have a swarm of ravens spawn around the targeted creature, causing any hostile creature within 10ft to make a DC 18 strength saving throw, and on a failed save they are pushed back 15ft, and on a successful save, they take 2d8 piercing damage.
This costs one Plague die.
A Plague of Ravens
Starting at the 14th level, as an action, you can summon a swarm of ravens that have different effects depending on your form.
If you have your mask on, the swarm of ravens are swathed in a green, wispy energy as they fly around, and one target per Plague dice used you can see within 60ft are poisoned, deafened, blinded, and frightened until your next turn.
If you are in Raven form, you fly with the swarm of Ravens, surrounding one target you can see within 60ft, and every raven in the swarm uses Plaguebringer's Eyes, dealing double damage of all the Plague dice rolled for this attack.
After using this action, you cannot use another action on your next turn, but can use bonus actions and reactions.
This attack costs all remaining Plague dice you have and can only be used once per long rest.
