Spellcasting:
3rd-level Justicar feature
Your conviction and faith allow you to produce divine spells, much like a cleric or a paladin does.
Cantrips: You learn two cantrips of your choice from the Justicar Spell List, and you learn an additional Justicar cantrip when you reach 10th level.
Spell Slots: The Justicar Spellcasting table shows how many spell slots you have to cast your spells of 1st-level and higher. To cast one of these spells, you must expend a slot of the spell's level or higher. You regain all expended spell slots when you finish a long rest. For example, if you know the wrathful smite spell and have both a 1st and a 2nd-level spell slot, you can cast wrathful smite using either spell slot.
Spells Known of 1st-Level and Higher: You know three 1st-level Justicar spells. The Spells Known column of the Justicar Spellcasting table shows when you learn more spells of 1st-level or higher, of a level for which you have spell slots.
When you gain a level, you can replace one of your Spells Known with another spell from the Justicar Spell List. The spell must also be of a level for which you have spell slots.
Spellcasting Ability: Charisma is your spellcasting ability for your Justicar spells.

Channel Divinity:
3rd-level Justicar feature
Also at 3rd level, you gain the ability to channel divine energy directly from your god, and can use it to fuel magical effects. You start with one such divine effect, Shroud of Faith.
Once you use your Channel Divinity, you must finish a short or long rest before you can use it again. Upon reaching 13th level, you can use it twice between short or long rests.
Shroud of Faith: As an action, you grip your holy symbol and invoke the protection of your god. You, and anything you are wearing or carrying, becomes invisible for up to 1 minute. This effect ends early if you attack or cast a spell.

Divine Sense:
3rd-level Justicar feature
The presence of evil registers on your senses like a noxious odor, and good rings like music in your ears. Starting at 3rd level, you can use a bonus action to open your awareness to detect such creatures in your presence. Until the end of your next turn, you know the location of any celestials, fiends, or undead within 60 feet that are not shielded from divination magic. You know the creature type of any creature whose presence you sense, but not its identity. You also detect the presence of any place or object that has been consecrated or desecrated, as with the hallow spell, within the same radius.
Once you use this feature you must finish a short or long rest before you can use it again. If you have no uses left, you can expend a spell slot of 1st-level or higher to use it again.

Consecrated Strikes:
9th-level Justicar feature
Your god has consecrated your weapons. Beginning at 9th level, when you hit a creature with an attack that includes Sneak Attack damage, you can expend a spell slot of 1st-level or higher to empower your strike with radiant judgment.
The additional damage from your Sneak Attack becomes radiant damage, and if you roll a 1 or 2 on any of damage dice for this attack, you can re-roll the die, though you must use the new roll, even if your new roll is a 1 or a 2.
