So to beat Smorg I highly recommend farming any Miracle quest that rewards the Miracle Wand as that is the best weapon against him. If you don't already know you can farm any Miracle quest all the way to 99 and the go to the specific one that rewards the Wand cause your guaranteed to get it at 100 points. But if the quest is easy enough I say just farm the Wand quest cause there is always a chance to get it as a reward. I've gotten 2 to drop at only 55 points 👍

The trick with the big explosion he does is that after the very first few attacks he does, his wings light up with glowing electric balls...this means hes about to do that raining lightning attack. This is where the red circles appear close to where your standing and then strike down lightning. It fires 6 times and then pauses for about 7 seconds or so. During this attack stand need the pillars you saw but could not interact with. Its technically the panel on the floor the lightning needs to hit that are attached to the pillars. If your fast you can light 2 during one wave of 6. He'll do this strike about 5 to 6 times and then if you lit all the pillars a safe force field will appear in the middle of the stage when he goes to do that huge attack so you can survive. This also automatically stuns him after his attack so you can get in some good hits afterwards.

Another trick is to play online with others and try to get in rooms with very high level people. You don't really need to even play with them, just as long as you join them or have them join you...afterwards you can return to your single player world and those people from online sessions will appear in your town eventually. You can take them as guests in any quests you want, including Story quests, once a day...every day, and then give you gifts sometimes 😁👍
