Roguish Archetype
At 3rd level, a rogue gains the Roguish Archetype feature. The following options are available to a rogue, in addition to those offered in the Player's Handbook and other books: the Divine Watcher.
Divine Watcher
Raised from a young age by the Order of Bahamut, rogues of the Divine Watcher archetype serve as the Order's secret weapons. Raised and trained with the purpose of under- mining the rebellion of upstart mages in Brasshorn, they serve as spies and assassins, fulfilling their grim duties in the name of the Lord of the North Wind.
Righteous Assault
At 3rd level, the divine energy that fills you guides your blade. You gain an additional way to use your Sneak Attack; while you are concentrating on a cleric or paladin spell, you don't need advantage on the attack roll to use your Sneak Attack. All other rules for Sneak Attack still apply to you.
Spellcasting
When you reach 3rd level, you gain the ability to cast spells. Cantrips. You learn three cantrips of your choice from the cleric spell list. You learn another cleric cantrip of your choice at 10th level. Preparing and Casting Spells. The Divine Watcher Spell- casting 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.
You prepare the list of spells that are available for you to cast, choosing from the paladin spell list. When you do so, choose a number of paladin spells equal to your Wisdom modifier + one third your rogue level, rounded down (minimum of one spell). The spells must be of a level for which you have spell slots.
For example, if you are a 7th-level divine watcher rogue, you have four 1st-level and two 2nd-level spell slots. With a Wisdom of 14, your list of prepared spells can include four spells of 1st or 2nd-level, in any combination. If you prepare the 1st-level spell bless, you can cast it using a 1st-level or a 2nd-level slot. Casting the spell doesn't remove it from your list of prepared spells.
You can change your list of prepared spells when you finish a long rest. Preparing a new list of paladin spells requires time spent in prayer and meditation: at least 1 minute per spell level for each spell on your list. Spellcasting Ability. Wisdom is your spellcasting ability for your cleric and paladin spells, as your magic is derived from devout devotiom. You use your Wisdom whenever a spell refers to your spellcasting ability. In addition, you use your Wisdom modifier when setting the saving throw DC for a cleric or paladin spell you cast and when making an attack roll with one.

Replicate Spell
Starting at 9th level, your training had allowed you to repli- cate spells you are unfamiliar with through observation and mimicry. You can attempt to replicate a spell that you have seen cast within the past 1 hour. The spells must be of a level for which you have spell slots.
Casting a spell in this way requires the spell's normal casting time, and expends a spell slot as usual if it is a spell of 1st-level or higher. Once the spell's casting time is completed, you must make a Wisdom check to determine whether you cast it successfully. The DC equals 10 + the spell's level (DC 10 for cantrips). On a failed check, the spell fails with no other effect.
If a spell doesn't appear on the cleric or paladin spell list, the spell is nonetheless a cleric or paladin spell for you when cast in this way.
Spell Slip
At 13th level, your observation of magics allows you to slip between the cracks to evade its effects. When you are subjected to a spell that allows you to make a saving throw to take only half damage, you can use your reaction to instead take no damage if you succeed on the saving throw, and only half damage if you fail.
By Providence
Beginning at 17th level, your connection to divine power graces you with blessings as you will it. You can use a bonus action on your turn to begin concentrating on a divine prayer (as if you were concentrating on a cleric or paladin spell, for the purpose of your Righteous Assault feature). For 1 minute or until you lose concentration, you can add a d4 to any ability checks, attack rolls, damage rolls, or saving throws you make.
