I currently have wyvern scale mail and like how it protects me from
Both piercing and elemental.
However, Im stuck on what to pair it with.
My thoughts:
Iron might/ Volcanic Plate helm (for increased normal defence to make up for lack of it on the wuvern)
Deadshot chapeu (For a good all round set with an undead bonus)
Valkyrie helm
I already have a 4 star piercing helm in the form of an Ash tail cap,
And a 4 Star shadow helm with the seraphic helm.
As for armour I have Vog and Ash tail.
This is not just for FSC And Im not worried about drawbacks.
(I can always get a trinket "_^)
One idea is to get a pure normal helmet, to give you the normal protection that you really want in an armor setup. But there is not much call for a normal+normal+piercing+elemental armor setup. Split non-normal pieces are unpopular because of this kind of problem.
My suggestion is that you get a normal+shadow helmet, to make a general-purpose set (all four damage types). So Dread Skelly, Valkyrie Helm, Crown of the Fallen, Deadshot Chapeau, etc.
I'm sad to say that, in the long term, you will probably not use either of these sets very much, because you will acquire better armor sets. So another possibility is to stop work on the Wyvern Scale Mail entirely, and switch to another line right now. It's not too late to switch. More than half of the cost in making a 5-star item comes in the final upgrade from 4-star to 5-star.
