Clobbering Blast.

Your patron makes a powerful alteration to your Eldritch Blast to synergise with your other talents. 

Your Eldritch Blast now counts as a Melee weapon attack, this attack still uses your charisma bonus, proficiency score and any other bonuses to your ranged spell attack rolls you currently have to determine whether you hit and may still fire as many shots that you could before as separate attacks while using the same attack action.
