Hey guys it's me after a long time!
So I've made and heated a Mega Magnus to level 9 and was originally gonna make an Iron Slug. But now I'm confused whether to make Callahan or Iron Slug. One problem I have with Callahan is that I can't seem to hit Wolvers with its charge. It's very frustrating and I'd rather make an Iron Slug. Second problem, I don't have a Piercing Sword so I have to make a Grand Flourish too.
On the other hand, if I make a Callahan, I can also make a Winter Grave(already have heated Tundrus lying around) and I've heard it's an amazing gun. I also can't waste orbs and money as I'm also aiming for the Chaos Set.
So, help me friends.
Callahan or Iron Slug? Callahan or Final Flourish?

There's no reason to make two piercing weapons - not while you're only starting your arsenal, anyway. Since you seem to be a hybrid sword/gunner, you'll probably be happier with a toothpick and the Slug. But why did you want a Flourish? With a name like "Snarby-Slasher", don't you already have a good Thorn Blade?
As a hybrid, one of your main uses for a gun will be to pick off otherwise-inaccessible turrets (puppies, howlitzers, polyps). That's not a job shadow or piercing weapons were meant for. You'll want an elemental or normal gun instead. That's another reason to go for a Slug. While a Winter Grave is a nice gun, it's probably lower priority.
If you can't hit a wolver with a Magnus charge, you won't hit one with a Slug or Callahan charge either. That's not an issue.
