Laser Domain

Clerics of the Holy Laser Domain founded the Order of the Laser Masters, and are seen as a force for good across the known galaxy,  Adherents of this domain promote the ideals of rebirth and renewal, truth, vigilance, and beauty, often using the symbol of the sun or the divine phenomenon known as god rays. Their gods are those closely tied to that of focused light like Pelor, Lathander, or Bahamut.

Bonus Cantrip

When you choose this domain at 1st level, you gain the light cantrip if you don’t already know it. This cantrip doesn’t count against the number of cleric cantrips you know.

Blinding Laser

Also at 1st level, you can manifest divine lasers between yourself and an attacking enemy. When you are attacked by a creature within 10 feet of you that you can see, you can use your reaction to momentarily blind them causing a laser to erupt from your armor before the attacker before it hits or misses. It must succeed on a constitution saving throw equal to your spell save DC or be blinded until the end of your next turn. An attacker that can’t be blinded is immune to this feature.

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.

Channel Divinity: Divine Tracers

Starting at 2nd level, you can use your Channel Divinity to call down lasers on your enemies, obliterating darkness and dealing radiant damage to your foes.

As an action, you present your holy symbol, and any magical darkness along the path of a laser is dispelled. Target up to 3 creatures that you are aware of within 90 feet of you. They must make a Constitution saving throw. A creature takes radiant damage equal to 3d10 + your cleric level on a failed saving throw, and half as much damage on a successful one. The damage is reduced by 1d10 for each additional creature after the first. Cover is ignored by each ray.

Improved Laser

Starting at 6th level, you can also use your Blinding Laser feature when a creature that you can see within 30 feet of you attacks a creature other than you.

Light Amplified Spellcasting by Emission of Radiation

Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.

Laser Show

Starting at 17th level, you can use your action to activate an eruption of lasers that lasts for 1 minute or until you dismiss it using another action. You emit bright light in a 60-foot radius and dim light 30 feet beyond that. Your enemies in the bright light have disadvantage on saving throws against any spell that deals radiant, fire, or radiation damage.
