I've been stuck at the Hall of Heroes four star mission for half a year now. I have no idea what equipment or weapon path to go down. Here's what I have:
50k crowns
15 Flawed Orbs of Alchemy
3 Simple Orbs of Alchemy
9 Advanced Orbs of Alchemy
8 Elite Orbs of Alchemy
2 Eternal Orbs of Alchemy
I've been using the Heavy Plate Shield because it has the most defensive power.
I also have the Swiftstrike Buckler.
I wear the Dusker Cap and the Gunslinger Sash.
I use the Super Blaster and the Tempered Calibur.
I am well aware that the Normal damage weapons are some of the weakest in the game. That's why I haven't just crafted further up my current path. I think I want to get into bombs but I'm really very undecided. I've recently been recommended the Shivermist Buster and it seems like a good one to go after. If anyone could offer me clear advice I'd really appreciate it.
Get a better sword first, possibly a Brandish-line with elemental damage (Out of the 3 choices I'd suggest Combuster), that will help you steamroll pretty much everything past 4*.
As for your secondary weapon you can go for Shiver/Blitz if you're already planning on a set to use at Vana, that will be your main source of income at 5* and once you're there you can easily get up every other equipment you feel like upgrading, else you can take up another gun you fancy, possibly something that deals either shadow or piercing so you won't have a hard time dealing with enemies that resist elemental damage, if you want to follow the bomber path then Dark Briar Barrage is a wonderful option too, it's a great bomb for damage dealing and since it has very low knockback it's also partyfriendly.
Another thing to keep in mind to save money at the beginning is that you just need 1 weapon to be 5* to unlock all missions so you should keep your secondary weapon at lvl 10 4* seeing as any 4* lvl 10 deals more damage than it's 5* counterpart until it reaches lvl 7.
TL;DR
If you wanna Vana Shiv:
4* Fire brandish lvl 10
5* Shivermist Buster, possibly lvl 5 at least
If you wanna Vana blitz:
5* Combuster possibly lvl 7 or higher
4* lvl 10 Strike needle
If you wanna do a good-in-every-situation set that focus on bombs:
4* Fire/Ice brandish lvl 10
5* lvl 7 or higher Dark Briar Barrage
As for the shield, either upgrade your cobalt to 5* to unlock all missions (Cheapest option since you won't have to waste money on recipes) then ditch it in favour of a Swiftstrike buckler or get something that has shadow defense as I can assure you it'll be your worst enemy.
Armor depends on your set of choice.
