Hubmiiran Opus Magnum Invocation

The weapon you conjure as your pact weapon can be a firearm (excluding Revolver, Bad News, and Hand Mortar).

Additionally, when summoned your pact weapon appears fully loaded and you may reload your pact weapon as a bonus action, it does not need to be repaired after it misfires, ranged attacks with your pact weapon deal force damage, and ranged attacks with your pact weapon can benefit from any invocation feature that effects eldritch blast (including Agonizing Blast).
