Hey, I'm really liking bombing, and am planing on running a 2 sword 2 bomb setup with the spiral demo set >> volcanic demo suit as my endgame. I'm pretty sure I want to go Shivermist Buster to get the Frost effect+for fire mobs, but what would be a good 2nd bomb for pure damage? Or, if the Shivermist Buster's effect is useless what is a good alternative "status inducer" bomb?
Good Endgame Bombs?
Nitronome offers the biggest range for pure damage, and has a relatively fast explosion rate.
Big Angry is smaller range, but the "second circle" reaches the "first circle" faster, meaning it explodes faster. It's also angry.
Irontech is pretty nice too, but is slower to explode, meaning it might ruin some rhythms. It does edge out Nitronome in damage, though, and has comparable range.
Specialty damage:
Graviton family bombs do quite a hefty amount of damage for what they are, but you have to remember that they're shadow. This means while they get a bonus to damage on beasts (This trumps wolvers easily, because you set it down, they warp behind you, and get sucked right in), but fails on things like constructs (which are some of the most annoying monsters for bombers imo. Stupid laser eyebeam robots).
Radiant Sun Shards is really high Damage but it's a "shard" type bomb, meaning that it shoots out spikes in directions. I find this to be the least useful because of the fact that the bigger the area, the less likely a shard is to hit.
As for status bombs you pretty much have a choice for poison, freeze, or fire. Freezing enemies means they don't move, allowing you to charge another bomb or let your friends beat on them (or get away!). Poison stops healing, so Menders/silkwings are pretty much useless around one, and bosses can't heal themselves either. Fire is a nice DoT but looking at endgame, is useless in Firestorm Citadel, makes oilers light on fire and do tons more damage, and doesn't tick as often as you wish it did, or for how much. Stick with freeze or fire-- they're the better of the three.
"what would be a good 2nd bomb for pure damage?"
The Nitronome would be a good candidate.
"Or, if the Shivermist Buster's effect is useless what is a good alternative 'status inducer' bomb?"
The Shivermist Buster is basically the epitome of Crowd Control. If you prefer another style of haze bombing, the Ash of Agni is for DoT, and the Venom Veiler excels at mass debuffing + anti-Silkwing/Mender.
