Holy Warrior

Holy Warriors combine the martial mastery common to all Fighters with the pious devotion of a Cleric, allowing them to draw on the blessings of a deity, pantheon, or other immortal entity through prayer and meditation.

Level 3: Spellcasting

Cantrips: You know 2 cantrips of your choice from the Cleric spell list. Whenever you gain a Fighter level, you can replace one of these cantrips with another Cleric cantrip. When you reach Fighter level 10, you learn an additional Cleric cantrip.
Spell Slots: Your have spell slots based on your Fighter level. You regain all expended slots when you finish a Long Rest.
Prepared Spells of Level 1+: You prepare the list of level 1+ spells that are available for you to cast with this feature. To start, choose a spell from the Cleric spell list. The number of spells on your list increases as you gain Fighter levels, as shown in the table below. Whenever that number increases, choose additional spells from the Cleric spell list until the number of spells on your list matches the number on the table. The chosen spells must be of a level for which you have spell slots. Your Domain spells don't count against the number of spells you can prepare with this feature.
(DnDBeyond handles the number of spells you can prepare in a somewhat inflexible way, and so it will display that you can prepare more spells than the table below allows. To reconcile this discrepancy, a number of your domain spells equal to the difference will count towards your prepared spells, even though they shouldn't. Just trust that the numbers add up and don't manually prepare your domain spells.)
Changing Your Prepared Spells. Whenever you finish a Long Rest, you can change your list of prepared spells, replacing any of the spells there with other Cleric spells for which you have spell slots.
Spellcasting Ability. Wisdom is your spellcasting ability for your Cleric spells.
Spellcasting Focus. You can use a Holy Symbol as a Spellcasting Focus for your Cleric spells.

Level 3: Blessed Arms

You learn a ritual that blesses a weapon. You perform the ritual over the course of 1 hour, which can be done during a Short Rest. The weapon must be within your reach throughout the ritual, at the conclusion of which you touch the weapon and speak a benediction over it. The ritual fails if the weapon is cursed or sentient with a different alignment than your deity. You may use a weapon blessed this way as a Divine Focus. You can have up to two weapons blessed this way at a time. If you attempt to bless a third weapon, you must end the blessing on one of the other two.

Level 7: Blessed Warrior

As part of the Bonus Action you use to activate your Second Wind, you may cast the Bless spell targeting only yourself, without requiring somatic or material components or spending a spell slot. It does not require concentration until the start of your next turn, at which point the spell ends unless you begin concentrating on it.

Level 10: Battle Concentration

When you cast a spell, damage can't break your concentration on spells until the start of your next turn.

Level 15: Divine Strike

Once on each of your turns when you hit a creature with an attack roll using a weapon, you can cause the target to take an extra 1d8 Necrotic or Radiant damage (your choice).

Level 18: War Magic

When you take the Attack action on your turn, you may replace some of the attacks with a casting of one of your Cleric spells that has a casting time of 1 Action. You may either replace one attack with a Cantrip or replace two attacks with a level 1 or level 2 spell.
