You can use a bonus action to create a pact weapon in your empty hand. You can choose the form that this weapon takes each time you create it (see chapter 5 for weapon options). You are proficient with your pact weapon while you wield it and counts as magical for the purposes of overcoming resistances and immunities. Your pact weapon can also be used as a spellcasting focus for your warlock spells. Your pact weapon disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.
You can transform one magic weapon into your pact weapon by performing a special ritual while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done during a short rest. You can then dismiss the weapon, shunting it into an extradimensional space, and it appears whenever you create your pact weapon thereafter. You can’t affect an artifact or a sentient weapon in this way. The weapon ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. The weapon appears at your feet if it is in the extradimensional space when the bond breaks.
When you cast a spell that has a casting time of one action and only targets one creature, you can deliver that spell through your weapon. Make an attack with your weapon when you cast the spell. The range of your weapon attack is unaffected by the range of the spell. On a hit the target takes damage from both your weapon attack and suffers the effect the spell cast through it.
Any spell attack required for this casting of the spell is considered to have hit the target. If the spell enables you to make multiple attacks in one action (ex. eldritch blast or scorching rays) then all attacks hit the target that was hit by the weapon attack. They count as a single attack for spells and features like Warlock’s Curse(Homebrew). If a spell allows you to make multiple attacks with your action over the course of multiple rounds (ex. flame blade or vampiric touch) then you make another weapon attack each time you take the action to make another spell attack on subsequent rounds.
If the weapon attack misses then the target is unaffected by the spell.
When you reach 10th level in this class, you can make a weapon attack as a bonus action after using your action to cast a spell of first level or higher, you can make this weapon attack even if you cast the spell through your weapon with the pact of the blade feature.
