Ripper

There's something about a ripper that defies all logic. They cause death and fear so brazenly, indiscriminately, yet are never really caught. When pursued by the law, their presence washes away in the rain, like they never existed in the first place. People will often pass them over on the street and not think a second thought about the bloodied hands they just shook. A dark magic lies at the core of rippers, allowing them to cause acts of great brutality in highly populated areas without so much as a shrug from the populace. It is a power rumored to be granted by Death himself. The nature of ripper crimes are bloody and visible, with the occasional act of thievery, though it is often a trophy that means nothing to everyone but the Ripper themselves; perhaps an organ. This makes them slightly more dangerous than assassins or mercenaries which have a more monetary background. Rippers are hunters at nature, whether their aims are practical or not, and they want others to see their results.

Phantom

Beginning at 3rd level, your elusiveness and boundless guile are present in how you present yourself as a persona separate from that of a killer who leaves traces yet is never caught. If you use your Cunning Action, you can use two of the allowed actions instead of just one. You also have reactions equal to your proficiency bonus.

Feint

Beginning 9th level, when an attacker hits you within melee range and you use your Uncanny Dodge, you may also follow up immediately with a retaliatory strike, making an attack at the creature as part of the same reaction.

False Feint and Strike

Not a movement of yours is unnecessary, even those that miss. They make new openings for you to strike at. Beginning at 13th level, if you would miss with a melee weapon attack, you can choose to give it a bonus equal to your Ripper Sneak Attack Die. Also, if an attack would hit you, you may use your reaction to give it a penalty equal to your Ripper Sneak Attack die, if the penalty would cause the opponent to miss, their turn ends. You may use this feature a number of times equal to your Dexterity modifier (Minimum of 1), regaining all uses at the end of a long rest.

Blood-lust

Beginning 17th level, when you get the drop on another creature and get your attack in, it feels good to kill. The blood you splay about excites you into a frenzy now, after having killed so much. When you deal damage with your Sneak Attack with a melee attack, you may attack one extra time while adding half your Sneak Attack to the second attack.

Ripper’s Strike

You develop a new technique unique to all assassin’s. Beginning at 3rd level, instead of using a d6 for sneak attack damage, you use a d4, at 9th level this increases to a d6, 13th level a d8, and at 17th level a d10.
