Pact of the Shield Revised

An alternative to the blade, some Warlocks prefer to focus on more defensive capabilities.

As a Bonus Action, you can conjure a pact shield in your hand or create a bond with a magic shield you touch; you can’t bond with a magic shield if someone else is attuned to it or another Warlock is bonded with it. Until the bond ends, you have proficiency with the shield, the shield grants the bound warlock an additional +1AC, and you can use it as a Spellcasting Focus. At level 10, the AC bonus increases to +2.

You can cast Shield without expending a spell slot a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a Long Rest. You may expend 2 uses of this feature to cast Shield on a creature within 30 feet of you that you can see, and that isn't behind more than half cover. You may cast the spell on yourself using a Warlock spell slot. 

You may use a Bonus Action on your turn to attempt to Shove a creature. The target must succeed on a Strength or Dexterity saving throw (it chooses which), or you either push it 5 feet away or cause it to have the Prone condition. The DC for the saving throw equals 8 plus your Charisma modifier and Proficiency Bonus. This shove is possible only if the target is no more than one size larger than you.

Your bond with the shield ends if you use this feature’s Bonus Action again, if the shield is more than 5 feet away from you for 1 minute or more, or if you die. A conjured shield disappears when the bond ends.
