Warchanter

The frenetic pace of battle can easily confuse and overwhelm, but the beating of drums, horns of trumpets, and resounding hymns of warchanters drive their forces onto victory. These bards understand combat as a beautiful art form and use their talents to enhance it, urging allies to withstand greater suffering and spreading their magic across the field of battle.

Bonus Proficiency and Specialties

When you select this archetype at 3rd level, you gain proficiency with History. If you are already proficient with History, you instead gain an expertise die . In addition, you gain additional specialties in History equal to your proficiency bonus, and you gain another specialty whenever your proficiency bonus increAases. 

In addition, you gain proficiency with medium armor, shields, and martial weapons.

Victorious Hymn

Also at 3rd level, your battle hymns take a different tone, now specially prepared for bloody fights and hard fought victories. You learn an additional battle hymn chosen from Table: Battle Hymns, counting your bard level as double for the purposes of which battle hymns you meet the prerequisites for. This battle hymn does not count against your number of battle hymns known. When you reach 8th level, you may change one of your battle hymns for a new Victorious Hymn.

Second Chorus

Starting at 6th level, you can turn your inspiring talents to the multiplication of magic. When you see a spell cast on an ally within 30 feet, you can use your reaction and expend a use of Bardic Inspiration to twin it. If the spell is of 3rd-level or lower, targets only that ally, and you are also within the spell’s range, you are also targeted by the spell. 

When you reach 14th level in this class, you can expend two uses of Bardic Inspiration to twin a spell to target a different ally instead of you.

Slaying Momentum

At 14th level, your thirst for battle can be overwhelming. When an ally under the effects of one of your battle hymns reduces a creature to 0 hit points, they regain hit points equal to your Bardic Inspiration die + your Charisma modifier.
