Pact of the Thief God

While rogues with the access and intellect can always pursue the path of the arcane trickster, such things require study and training, and sometimes a thief simply needs to make a deal. Binnerot loves a bargain, often offering his power to a given guildmember or thief when he finds them at their most desperate. His gifts include boons to stealth and invisibility, secrets of poison and skill. A telltale sign a thief has made a deal with Binnerot is a silver set of thieves tools that are somehow always on hand in a moment of crisis. 

A deal with Binnerot can be as much of a boon to a master thief as a novice, an assassin without an exit strategy, or the cornered burglar have often heard a whispered offer from the god of thieves who is always willing to help assuming you can pay for his aid. Contracts with Binnerot often include daily offerings of silver or gold, woe to those warlocks who find themselves in debt to the god of thieves, who might seek payment in the form of favor, service or blood should he find his warlocks coin poor.

Binnerot's Knack

When choosing this subclass choose any skill you are not proficient in and gain proficiency. 

After choosing this additional proficiency, choose any skill or tool with which you have proficiency and gain expertise in that skill.

Silver Lockpick

Starting at the 1st level once per short rest as a bonus action summon a set of spectral silver thieves tools to your hands. These flawless tools are invisible to others and will remain bound to you for 8 hours after which they crumble into dust. 

While wielding these tools you gain the following benefits:

• If you lack proficiency in thieves tools, while using these tools you roll as though proficient, if proficient in thieves tools you roll with expertise using these tools, if you have expertise in thieves tools, you turn any disadvantage on a check made with these tools to a flat roll. (though any conditions that create disadvantage persist meaning you cannot turn a disadvantaged check to an advantage check)

• Any lock being augmented by an arcane lock spell is susceptible to the magic of the silver lock pick, objects with arcane lock cast on them gain no benefits against the silver lock pick.
• The Silver Lockpick also functions as a spellcasting focus for warlock spell

 

Thief Step

• Misty step is automatically added to your spell list
• You can cast it a number of times equal to your proficiency bonus without expending a spell slot,
• If you are hidden when using "Thief Step" Misty Step's Range is doubled

Burglars Bag

 

Starting at 6th level Binnerot blesses you with a small mimic that functions as a living bag of holding. 

The mimic has an extradimensional stomach capacity of 200 cubic feet and can swallow anything that fits in a 5ft by 5ft sq and doesnt exceed its stomach capacity in volume. 

The mimic can use an action to regurgitate a requested item it is holding. 

Unconscious or Deceased creatures swallowed by the mimic will be digested as though they are food unless you succeed on a DC 15 animal handling check to persuade the mimic otherwise. 

The mimic can also be deployed as an ally in battle it has hit points equal to (5 x Your Warlock Level +10) but otherwise has a normal mimic Statblock. If the mimic is reduced to 0 hp roll a d20 on an 11 or higher your items are regurgitated onto the material plane on a 10 or lower, your items scatter out into the astral plane. Binnerot can provide a new mimic upon the completion of a short or long rest. 

Emergency Exit

Once per short rest you can cast Passwall without expending a spell slot,

when you cast pass wall using the "Emergency Exit" ability you can choose any one of its three dimensions to double.

When you cast Passwall using "Emergency exit" the entrance and exit(if it has an exit) to the tunnel are covered by a silent image so it appears as though there is no passage.

You can also use "emergency exit" by expending a warlock spell slot. 

Friendly creatures who enter the "Emergency Exit" increase their movement speed by 10ft and maintain this bonus for an hour after entering. 

Cunning Curses

Starting at 14th level you have become adept at using your magic from hiding:

• Saves made against your spells are rolled at disadvantage if you are hidden from your target(s)
• Spellcasting does not reveal your location, bolts  and other spell effect appear to come from around random corners, or out of random patches of shadow, verbal components are perceived as unintelligible whispers emanating from the ether.
