My DM and I are having a disagreement over how the pact weapon from Pact of the Blade (PotB) is summoned.
Specifically, as a Hexblade with PotB, when I choose to summon my pact weapon as whatever - sword, axe, anything - do I have to roll a d20 to see if I successfully call it to me, regardless of whether I'm changing its form or if I'm recalling its previous form?
I've done some looking into the subject and haven't found a single reference to any such role being necessary. The description of Pact of the Blade (under the Pact Boon feature) states:
You can use your action to create a pact weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it [...]
Am I missing something?
His view seems to be PotB is the same as the pact I've made with my Patron (aka simply the fact I'm a warlock and that's the backstory of how we have/do magic) and thus just as I need a DC to cast, say, eldritch blast, or any other spell, I need one to call/summon my PotB pact weapon.
Do I need to roll any dice when I summon my pact weapon?
