Well, I'm not really a new player here, but seeing as I almost completed my sword-set I felt like going torward the bombing path and I need suggestion on which bombs I should grab and which bomber set is the most versatile (I don't really intend to make a ton of sets so I wanna know which one works good in every situation.
So far I got a Shiver and I'm planning to make a Dark Briar Barrage bomb, anything else I should get?
A common sword user turning to demolition?
Exquisite.
See this, this, relevant bombing equipment here, and listen to this while reading.
If you use bomb charge trinkets and/or charge UVs on your bombs (ideally +4 charge from trinkets and UVs) you can use Mercurial Demo without worrying about it, but otherwise you would decide between Volcanic and Mad Bomber. VDemo is usually preferred for the +2 charge (per part) and fire resistance while MadB has +2 bomb charge and +2 bomb damage per part but has less normal defense and several status weaknesses. Whether you get VDemo is up to you, you can get into bombing while upgrading an SDemo set then make it MadB at 5*. Or, again, if you can afford a combination of charge UVs and/or bomb charge trinkets, go for Mercurial Demo for that extra move speed; not that it makes a huge difference, but it helps a little. MDemo also gives a little bomb damage and has shock resistance. Read those linked threads.
