warning: long backstory, skip this paragraph to get to the good part
currently, I've been playing bomber all my life, no swords, no guns, nothing (except this past week where I found out about catalyzer). I'd always have my trusty fiery atomizer on me at all times and a secondary haze bomb like lightning or freezing. I would usually just place the fiery around the place and alternate with lighting to add extra dps, or use freezing in case of fiends or kats. My only problem was fire levels. Id have to do like freezing and a blast bomb which I wasnt very good at using, and my friends all hated it because of the explosion, so i tried to use it minimally, and even when I tried, it was just really annoying to me too.
Tl;Dr: I really hate the bomb knockback.
I really dislike it when enemies are flung around or thrown all over the place, but just the pure damage of haze bombs, so I thought of 3 new bombs
_____rock spike bomb________
when detonated, makes a field of spikes from the ground (lasts as long as a haze bomb)
deals piercing damage
_____radiant bomb___________
when detonated, releases a blinding light (lasts as long as a haze bomb)
deals elemental damage
_____dusk bomb_____________
when detonated, release a shroud of darkness (lasts as long as a haze bomb)
deals shadow damage
Have you considered using Dark Briar Barrage and Dark Retribution.
