Ninja (Rogue w/ Artificer spellcasting)

Ninja are the magicians of the martial arts world, specializing in the use of tools, tricks, and talent to make their way in a dangerous world. As a Ninja, you gain spellcasting that works like an artificer -- you have to use your tool proficiencies to cast your spells and make your items. In addition, you roll these tools up into your martial art, allowing you to use your ninja tools along with your sneak attack, which mechanically means you can sneak attack with your melee or ranged spell attacks. Finally, you continue to gain tool proficiencies in order to vary your abilities, as well as to make your ninja tools less expensive to create.

Spellcasting

When you reach 3rd level, you gain the ability to cast spells. See Spells Rules for the general rules of spellcasting and the Spells Listing for the artificer spell list.

Cantrips

You learn three cantrips.

Spell Slots

The ninjas Spellcasting table shows how many spell slots you have to cast your artificers 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 1st-level spell charm person and have a 1st-level and a 2nd-level spell slot available, you can cast charm person using either slot.

Spells Known of 1st-Level and Higher

You know three 1st-level artificer spells of your choice, two of which you must choose from the enchantment and illusion spells on the artificer spell list.

The Spells Known column of the ninja Spellcasting table shows when you learn more artificer spells of 1st level or higher. Each of these spells must be an enchantment or illusion spell of your choice, and must be of a level for which you have spell slots. For instance, when you reach 7th level in this class, you can learn one new spell of 1st or 2nd level.

The spells you learn at 8th, 14th, and 20th level can come from any school of magic.

Whenever you gain a level in this class, you can replace one of the artificer spells you know with another spell of your choice from the  artificer spell list. The new spell must be of a level for which you have spell slots, and it must be an enchantment or illusion spell, unless you’re replacing the spell you gained at 3rd, 8th, 14th, or 20th level from any school of magic.

Spellcasting Ability

Intelligence is your spellcasting ability for your  spells, artificer since you learn your spells through dedicated study and memorization. You use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for a  spell artificer you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Ninja Arts

You learn a style of martial arts that focus on speed cunning and the use of ninja tools. To this end, add your intelligence bonus to your armor class (provided you are not wearing armor or a shield), gain proficiency in alchemist tools, and you may make a sneak attack when making a melee or ranged spell attack. 

 

Ninja Technique

Your unarmed strike now does 1d6 damage. Should you successfully grapple, trip, or disarm an opponent, you may immediately make an unarmed, melee, or melee spell attack with advantage.

Gain an addition Tool proficiency.

Ninja Tools

Use spells you can't cast to create magic items. This spell can be from any class spell list, but can not be of a level you can not cast.

For any and all magic items you create that are on your spell list, you may make an Arcana check vs. 12 + the spell level. If you succeed, you may make the item for half of the cost in resources and half the time. 

Also, gain proficiency in a tool of your choice. 

Tool Master

 Gain an additional attunement slot, and use your own spell slots to replace charges on magic items. One spell slot equals one charge. In addition, if the item is a one use item that recharges daily, you may recharge during a short rest. You may only use this ability once per long rest.
