Mugen Tenshin[edit]

The Mugen Tenshin clan is a prominent clan of shinobi, located within the mountains. A secret society, only certain groups such as the Hayabusa clan, and the Black Spider clan know of them and their capabilities. The clan has existed for eighteen generations. As with all shinobi clans, the Mugen Tenshin clan is governed by a group of master shinobi, with the lower shinobi "troops" ranking from greater shinobi to lesser shinobi. The master shinobi govern the clan’s activities both within and outside the village, and are regarded with respect by other members of the clan.

Creating a Mugen Tenshin[edit]

The Mugen Tenshin has two different styles Tenjinmon and Hajinmon

Tenjinmon ("Heavenly God Gate") is the foreground perspective of Mugen Tenshin style ninjutsu. Most ninjas from the Mugen Tenshin clan belong to this perspective. Tenjinmon practitioners train in order to acquire superhuman physical strength and battle technique and are highly resistant to physical pressure. this style gets to choose Strength Save proficiency instead of Dexterity Save, and uses Strength or Dexterity for attack rolls as well.

Hajinmon ("Supreme God Gate") is the background of Mugen Tenshin style ninjutsu and is considered a secret style within the Mugen Tenshin clan. Hajinmon practitioners possess the same capabilities of Tenjinmon practitioners. However, the style is a lot less direct in attacks with emphasis on stronger ninpo abilities. The ninja of the Hajinmon style, despite possessing unbelievable powers, provide background support and loyalty to the Tenjinmon ninja. Gets to add 1d4 to all Ninpo attack rolls and damage

Torn Sky Blast (Ninpo)[edit]

A deadly ninpo technique that allows the user to generate a large lightning-like blast of energy from their hands and shoot it toward their target dealing 1d4 + Dexterity modifier (at level 11 it becomes 1d8 + Dexterity modifier). The color of the energy summoned differs from person to person.

Sneak Attack[edit]

Beginning at 1st level, you know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.

You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.

The amount of the extra damage increases as you gain levels in this class, use the Rogue class Table for this classes sneak attack as well.


At 1st level, choose two of your skill proficiencies, or one of your skill proficiencies and your proficiency with any of your tools. Your proficiency bonus is doubled for any ability check you make that uses either of the chosen proficiencies.

At 15th level, you can choose two more of your proficiencies (in skills or with any of your tools) to gain this benefit.


At 1st level, your practice of martial arts gives you mastery of combat styles that use unarmed strikes and ninja (Shinobi/monk) weapons, which are shortswords and any simple melee weapons that don't have the two-handed or heavy property.

You gain the following benefits while you are unarmed or wielding only ninja (Shinobi/monk) weapons and you aren't wearing armor or wielding a shield:

You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes and monk weapons. You can roll a d4 in place of the normal damage of your unarmed strike or monk weapon. This die changes as you gain Mugen Tenshin levels, Level 1-4 1d4, Level 5-10 1d6, Level 11-15 1d8, Level 16-20 2d8 When you use the Attack action with an unarmed strike or a ninja (Shinobi/monk) weapon on your turn, you can make one unarmed strike as a bonus action. For example, if you take the Attack action and attack with a quarterstaff, you can also make an unarmed strike as a bonus action, assuming you haven't already taken a bonus action this turn. Certain monasteries use specialized forms of the ninja (Shinobi/monk) weapons. For example, you might use a club that is two lengths of wood connected by a short chain (called a nunchaku) or a sickle with a shorter, straighter blade (called a kama). Whatever name you use for a monk weapon, you can use the game statistics provided for the weapon.

Gain Feat[edit]

Chose 2 Feats at first level then gain one every forth level till level 12

Cunning Action[edit]

your quick thinking and agility allow you to move and act quickly. You can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.

Shinobi Speed[edit]

Art of the Raging Mountain (Ninpo)[edit]

A very powerful and mortal technique that allows the user to draw in energy from the surrounding area and expel it in a large blast of energy around themselves deals 3d6 damage + Constitution modifer to all within a 30ft radius (at level 14 add 2d6 to damage), they can make a Dexterity save to take half damage and need to make a Strentgh save to keep from getting knocked over. Dexterity DC is 15 or better, Strentgh DC is 15 or better. This takes a full round to prepare and will not happen till the end of your turn that round, requires a concentration check if hit while trying to enact.

Teleportation (Ninpo)[edit]

Teleportation abilities used by some of the shinobi allow the user to leave one place and arrive at another without the need of walking, usually used for travelling long distances or for a quick escape from danger. Actions performed for teleporting differ from person to person: used as a Standard Action, and can only be done in combat once an encounter, with a maxium distance of 100ft (unless disengaging) if used to disengage then you can't rejoin the battle even if party memberss are still there.
