Yes. First of all you can face all the bosses at any time just because there isn't any timeline in War Mode. This will be solved out if people would like to start discusion about what and when. We need a point when everything changes. Like Plantera.

I know it. I found some nice materials. There aren't many of them though : /

Spirits - Since souls are more Hard Mode related and spirits are more innovative.

Adamantite Gun Parts - A perfect War Mode ingredient for guns. I would really like to see it.

Shark Scale - Is a material dropped by the boss although it would be good one for making other weapons and stuff just like Hallowed Bars used to be prieviously.

Steel Bar - From Wall of Steel. I would like to see them in every early Crafting Recipe.
