In that case...
[ ] Hit Leviathan with your absolute most powerful blast. Sacrifice accuracy for power, and hope you can compensate through luck manipulation.
Looks good. Catch him while he's still moving on the ground using our trump card to make this one count. I like it.
[ ] Your telekinesis isn't great at catching moving foes, but it's worth a shot. If you manage to throw him in the air for just a few seconds, that might give you the opening you need to win this.
More of the same. Leviathan is ready to face this tactic now. No.
[ ] Leviathan thinks it's safe in the ocean. That's because he's never fought an angry god. Use your secondary power pool to turn insubstantial, then follow him at hypersonic speed, unhindered by water.
The benefit here is "having as much time as it takes to blast him good" which is nice. Compares to the first option. Instead of taking our shot when it's still aboveground, we take our time to line it up as best as possible.
[ ] If he leaves, it's a victory - it means the city survives. Focus on helping people for now; there will be other opportunities to fight him.
With Panacea back on her feet, I don't think that's necessary. We can use this chance to put him down. Let's try to take it.
For now I'm going with
[x] Leviathan thinks it's safe in the ocean. That's because he's never fought an angry god. Use your secondary power pool to turn insubstantial, then follow him at hypersonic speed, unhindered by water.
in great part because it is cool as hell.
Also, I'd normally get right on finishing my own update in response to this one, but it's way past midnight here, and I have a train to catch in about 7 hours. So I'll do that later.
So tell me, Sun Tzu, which one do you want me to do? Conquest training montage, Tale of Two Worlds with the protagonist starting to get a feeling for how bad the situation is, or Eleonor!Illyria's rampage across the academy and her fight against Colbert of the flame snake? I've done the prep-work on all of these, so I can post any of them tomorrow. You get to choose which one.
