Where You Should Use Excalibur
As for how you should use Excalibur once you have it in Spelunky 2, it depends on what run you’re looking to complete.
If you’re looking to complete a standard run of the game, then Excalibur will serve you well. It acts as a one-hit-kill melee weapon and can defeat most anything from Yetis and Mech-equipped Aliens to the final boss of the game.
On the other hand, if you’re out to unlock secrets, then the Excalibur can still be vital.
In one of the game’s secret Zones known as Abzu, you’ll encounter the boss enemy Kingu. He’s unkillable by standard means, but you can bring him down with the Excalibur, after which he’ll drop the Tablet of Destiny, an item needed to unlock one of the game’s secret bosses and endings.
