Pact of the West

Warlocks that follow the Pact of the West are granted access to Pact Weapons in the shape of Firearms. You may summon either a long range rifle or a pair of short range pistols. These Warlocks specialize in ranged combat and quick reflexes to quickly take down enemies and get out alive.

Quickdraw

When you reduce an enemy to 0 hitpoints, you gain one point of Favor. For each point of Favor, reduce the number needed for a critical hit by 1. This effect stacks and resets after a long rest.

Saddle Up

Hard to get around the planes without a reliable mount. You gain access to the Find Steed spell. The duration of the spell is extended until dismissed. You may cast this spell as a bonus action. If you or your mount are reduced to 0 hitpoints, you must wait 8 hours before casting it again.

Between a Rock and Hard Place

These lands are unpredictable and a blue sky can turn black in a heartbeat. You're always looking over your shoulder, ready for danger at the drop of a hat. When you make an ability check or a saving throw, you can use this feature to add 1d10 to your roll. You can do so after seeing the roll but before any of the roll’s effects occur.

You can use this feature a number of times equal to your Charisma modifier (minimum of once), but you can use it no more than once per roll. You regain all expended uses when you finish a Long Rest. 

Frontier Justice

Someone messed up big time, or else you wouldn't be on their tail. Mark an enemy within 100 feet of you within sight or by using personal objects belonging to the target. This mark lasts for 1 hour. You may use this ability a number equal to your Charisma modifier. Gain advantage on checks made to track that enemy. You have a general idea of the direction and speed that the target is moving. You have advantage on strikes made against that enemy. If the enemy dies while marked, you gain health equal to the amount of damage you did to that enemy while marked. Uses reset upon a long rest. 

Red Right Hand

Once per day, you may double your proficiency bonus to attack and damage rolls. This effect lasts for 30 seconds and resets if an enemy is reduced to 0 hitpoints by a critical hit.
