A question came up in my last gaming session about conjurations. I looked around online, but can't locate a clear answer on this.
There's another wizard besides myself in our party and he tried to attack with Bigby's Icy Grasp, but missed the attack roll on the turn he activated it. I asked him why he didn't but a marker on the game map to show where the hand was and he said that since he missed, it failed to appear. I was under the impression that even if a conjuration missed with its attack the turn you activate the proper spell, the conjuration still appears and you can try again on your next turn to make the attack with it (using the sustain action when needed).
My question is: Who's right? Does the Conjuration still appear on a miss or not?
Thanks in advance.
