Martial Archetype - Chanter
The power of words can inspire friends and demoralise foes, and few know this better than the Chanters. Utilising mystic chants, the Chanter weaves sword and song together to aid their allies to victory. Chanters of exceptional strength can learn to disrupt spells, push their allies beyond their normal limits, and even call back the dead from the beyond.
Chants
When you take up this archetype at 3rd level you learn how to use Chants, special words of power that resonate with the frequency of reality. At 3rd, 6th, 9th, 12th, and 15th levels you learn a number of Chants. You can choose to sing up to two chants in place of one attack on your turn. Chants affect all creatures you choose who can hear you. The effects of a Chant last until the start of your next turn. Silence or other sound disruption affects can prevent you from using your Chant.
At 5th, 11th, and 17th levels you add another chant to your song, totalling at 5 separate Chants in place of one of your attacks.
Performer
When you take up this archetype at 3rd level you gain proficiency in the Performance skill. If you already had this, you instead gain proficiency in one other Fighter skill of your choice. In addition, you can attune to any magical items that require the Bard class, even without having any Bard class levels.
Swift Word
Once you reach 7th level you can unleash a chanted word at a single target as a bonus action. Instead of affecting all creatures who can hear you, it instead takes effect solely on that target.
Overwhelming Word
At 10th level when another creature that you can hear casts a spell with a verbal component, you can use your reaction to speak an Overwhelming Word. If the spell level is equal to or lower than your proficiency bonus, it is instantly negated. If the spell level is higher, you must succeed on a DC10+Spell level charisma ability check to negate it successfully.
Overwhelming Word can be used once, refreshing on a short rest.
Universal Voice
From 10th level the power of your voice allows you to touch the minds of others. You learn how to speak (but not read or write) a language simply by exchanging a few words with a speaker.
Word of Release
At 15th level you learn a word that allows individuals to push past their own limitations. As an action you can speak a word of speed to one ally who can hear you. They can then use their Reaction to take one Action of their own.
This feature can be used once, refreshing on a short rest.
Grand Chant
When you reach 18th level you learn how to utilise Grand Chants. Upon completion of a long rest you can choose one from the list below, which you can use once as an action on your turn. You must complete a long rest before being able to use your Grand Chant again.
Light of Dawn: This hymn brings hope to those lost. Any dead creatures within a 30' radius that you choose return to life at half their maximum hit points, so long as they have not been dead more than 10 days. This does not restore missing body parts but does cure all non-magical poisons and diseases that might be in their systems.
Great Gale: Your voice heralds a great wind. You can cast the Whirlwind spell without any material components. So precise is your control that you can choose to exclude any creatures from its effects when you summon the winds in this way. It also does not require Concentration, but does end instantly if either you or the Tornado enters an area of Silence.
Hero's Call: This mournful dirge allows you to summon forth the spirit of a long dead hero to fight on your behalf. This spirit uses the statistics of the Death Knight creature (MM). It acts on its own initiative and can be commanded verbally at no action. If you do not command it, it acts in what it judges to be your best interest. Once the spirit is reduced to 0 hit points or one minute elapses the spirit collapses to dust.
