TEXT:  
  Divine Domain 
  In a pantheon, every deity has influence over different 
  aspects of mortal life and civilization, called a deity’s 
  domain. All the domains over which a deity has influence 
  are called the deity’s portfolio. For example, the portfolio 
  of the Greek god Apollo includes the domains of 
  Knowledge, Life, and Light. As a cleric, you choose one 
  aspect of your deity’s portfolio to emphasize, and you are 
  granted powers related to that domain. Your choice might 
  correspond to a particular sect dedicated to your deity. 
  Apollo, for example, could be worshiped in one region as 
  Phoebus (“radiant”) Apollo, emphasizing his influence over 
  the Light domain, and in a different place as Apollo 
  Acesius (“healing”), emphasizing his association with the 
  Life domain. Alternatively, your choice of domain could 
  simply be a matter of personal preference, the aspect of the 
  deity that appeals to you most. 
       Each domain’s description gives examples of deities 
  who have influence over that domain. Gods are included 
  from the worlds of the Forgotten Realms, Greyhawk, 
  Dragonlance, and Eberron campaign settings, as well as 
  from the Celtic, Greek, Norse, and Egyptian pantheons of 
  antiquity. 
  Festival Domain 
  It is said that, many years ago, clerics used the bright lights 
  and thunderous noises of fireworks to frighten off evil 
  spirits. Nowadays, of course, clerics have developed far 
  more effective tools for turning the undead and banishing 
  the demonic, and fireworks have morphed into a form of 
  entertainment for the masses. Such is the popularity of the 
  so-called 'fire festivals' that there is now a whole clutch of 
  demigods dedicated to them, complete with monastery-like 
  alchemy labs and a priesthood that travels the land selling 
  rockets and sparklers.

  Festive Atmosphere 
  When you choose this domain at 1st level, people begin to 
  feel much more at each around you. When you use the Help 
  action to assist another creature, you can use a bonus action 
  to grant them temporary hit points equal to your Wisdom 
  modifier. These temporary hit points last for as long as you 
  remain within 30 feet of the creature or until the creature 
  takes a long rest. 
       You can use this feature a number of times equal to your 
  Wisdom modifier (a minimum of once). You regain all 
  expended uses when you finish a long rest. 
  Prismatic Spellcasting 
  Also at 1st level, whenever you cast a spell that would deal 
  radiant damage, you can change the damage type to acid, 
  cold, fire, lightning, or poison. 
  Channel Divinity: Firework 
  Starting at 2nd level, you can use your Channel Divinity to 
  conjure a small explosive, which you can throw into any 
  space within 60 feet as an action. When you do so, each 
  creature within 10 feet of the target point must make a 
  Constitution saving throw or be blinded and deafened until 
  the start of your next turn. The firework emits a loud boom 
  that can be heard up to 300 feet away. 
  Demon Seal 
  At 6th level, your Turn Undead and Destroy Undead 
  features also work against fiends. 
  Potent Spellcasting 
  At 8th level, you add your Wisdom modifier to the damage 
  you deal with any cleric cantrip. 
  Grand Finale 
  Starting at 17th level, when you make a ranged attack or 
  cast a cantrip that targets only one creature, you can cause 
  the projectile or the cantrip to explode in a shower of 
  sparks. Each creature within a 5-foot radius centered on the 
  target must make a Dexterity saving throw against your 
  cleric spell save DC or take damage as if also targeted by 
  the attack or cantrip.
