They dress sombrely, and often eschew fancy clothing or the usual trappings of life, seeing such things as pointless distractions. Dirgist recitations can sometimes be heard at night, echoing eerily through the avenues of cemeteries, or ghosting across the mist shrouded fields of recent battles. A few choose to travel with adventurers; only too aware of their oft' brutal and pain filled lives, eager to experience their suffering with them, and to document it in rhyme, song and writing.
ACCEPTING OF DEATH
When you become a Dirgist at 3rd level, you learn to accept that death is inevitable, even if you are brought back by magic or other unnatural means. You accept that nothing, not even reality itself is truly eternal, and as such, lose any fear of life, death or even suffering. As such, you become immune to all fear based effects, including the frightened condition, intimidation or the effects of spells such as Phantasmal Killer.
At 3rd Level you can infuse those that oppose you with terminal despondency so profound that they actually die a little. As a reaction to an enemy within 60ft of you starting their turn, you may expend one use of your Bardic Inspiration, and inflict psychic damage on that target equal to the result of that dice being rolled. A creature is immune to this if it cannot hear you, or is immune to being frightened / fear effects.
In addition, you can expend one use of your Bardic Inspiration ability as a bonus action, to mantle yourself in the aura of death for 1 round. Whilst this is in effect, undead suffer disadvantage on attack rolls against you, and you gain Resistance to necrotic damage.
VOICE OF THE DEAD
At 6th level, you have listened to the whispered voices of the dead, and have learned how to speak with them. As an action, you can expend one use of your Bardic Inspiration to cast Speak with Dead as a spell like ability.
CALLER OF THE DEAD
At 14th level, the dead know you and will fight for you. As an action you can expend one use of your Bardic Inspiration to cast Animate Dead at 3rd level as a spell like ability. If you wish, you may expend up to 6 additional uses of your Bardic Inspiration to cast the spell at a higher level (+1 level per use expended).
At 16th level, you can instead choose to sing a dismal song that takes one minute (you cannot do anything else during this time, as if you were casting a spell), after which you may expend two uses of your Bardic Inspiration. By doing this, you can can cast a Create Undead spell. At 18th level you can expend three uses to cast it at 7th level, and at 20th level can expend four to cast it at 8th level.
