Spirit sword?????

[Madine]

How does one kill some enemies/bosses with this and no full health (so no projectile).

Some enemies like those in the corpse with poisonous area around them, ok, maybe bombs.

But then how do you deal with third phase of Rotgut with just the sword???

At the moment I'm thinking of avoiding this item entirely, unless there is something I'm missing here...

going to have to use the charge shot attack with the sword if the enemy is out out range and there's no other way to hit it which always fires a projectile.

Charge attack destroys projectiles, I defeated Delirium(Or Mega Satan not sure...) without getting hit with the sword abuse the charge attack.

That's what I'd consider "something I was missing", Thanks!

The poison gas doesn't instantly damage you, that happens if you're staying long enough in it, so you can use the charge attack on them.
I think spamming the attack works too, but the charge attack is likely best there and something you need to build muscle memory with, because of how useful it is.

As for phase 3 of Rotgut, you need to use the platforms, so again either a charged attack, or spamming the slash when you're falling down.
The easiest way I guess would be to get flight on your run somehow. :p
