I recently decided to take up bombing after finding a black kat cowl (and getting a bit bored of gunning and slashing everything for 300+ hours) and getting a volcanic demo suit. Now, so far I have the following bombs:
-Nitrome
-Dark Briar Barrage (my favorite so far)
-Dark Retribution (already had)
-Electron charge
-Shivermist Buster (already had)
-Fiery Atomizer (found in a Vana run)
So far so good, but I noticed there were no elemental damage/blast bombs so a guildie recommended me making an Electron Vortex as a utility/damage bomb... the problem is that I despise LD and get the 250 tokens is just gonna be horrifying (unless I sink like 900 ce in krogmo coin boosters to make the grind a lot faster), but then another guildie told me about the Deadly Cristal Bomb, an elemental shard bomb... the problem with that is that it's a shard bomb (I used to had a sun shard starting out to take care of trojans but the update kinda ruined them for me so I sold it soon after).
So now I'm in a bit of a pickle: do I shallow my words and just try to get used to the shard bombs and get a DCB or should I force myself to grind LD and throw my sanity away to get an Electron Vortex? Which would be a better investment in the long run? Should I just go and say SCREW THAT and just run with a Polaris for elemental damage?
You don't need an elemental fast-damage bomb. For fast damage use Nitronome on constructs or DBB on undead. For slower damage use Ash of Agni or Voltaic Tempest.
That said, every bomber should have either Graviton Vortex or Electron Vortex, and EV is slightly better. So consider getting EV although you hate PvP.
I've never used DCB, but I've used Scintillating Sun Shards, and I was not thrilled by the effectiveness or the fun.
