If you have enough critical hits, use Whale Hunt

To hunt whales with nuclear explosions, if there is a lack of critical hits at other times, use the Star Crossbow. If the critical hits are sufficient, use Heroic Spirits. Heroic Spirits are a direct physical attack bonus.

If it were 20% of this damage, it would be a sure kill.

The only problem is that this weapon is very difficult to get, and it is even more difficult to get full stars. I don’t have any.

Whale hunting has a stable damage increase of 20%
