A lot of bombs are lacking in their power. While I am a bomber main, I would like to see bombing expanded upon.
ASI changes
The first change with this update is that ASI can now be rolled on bombs. And will reduce the fuse time of all bombs. Imagine how fast that Nitronome will explode! This will make bombs like shards and Bab much more viable.
New Armor Sets
Shadow Defense + Shock Resistance + ASI VH demo set. Allows for really quick detonations.
Big Bomber Armor Set. Grants Damage Bonus Maximum and CTR Med for bombs. However, also grants ASI Decrease Very High for bombs. This set will allow you to build up a ton of powerful bombs on the ground.
New Bombs
Flash Freeze, Solar Flare, and Thunderwave. These are status variants of Nitronome. Flash Freeze is Elemental + Freeze. Solar Flare is Elemental + Fire. Thunderwave is Elemental + Shock. They each have a good chance to cause moderate status.
Burst Bomb family. This bomb line works like old shard bombs. It has Normal Damage and Piercing Damage lines.
Pulse Bomb family. They release 3 pulses of damage within a radius, dealing damage to all enemies before dying. It has a Normal Stun line(Bulldozer) and a Normal Fire line(Flamethrower). Dealing strong status.
I'm going to try to be gentle. I like that you're suggesting things and think that you're a great person.
A lot of bombs rely on their fuse time and are balanced around that. Nor is longer fuse time a bad thing always. I would say that the shard bomb's longer fuse time, if rewarded better, would be a good defining feature for them. Irontech destroyer and nitronome are balanced around their fuse times as well. Detonating faster would be fun, but I worry that it would break the balance of the game.
My personal idea that I hate to be pushing because it's out there and has been forever is bomb storage- you charge a bomb and store it, then attack with the bomb to place one of it on the ground. The special bomb stat would be bomb storage, you'd start with the ability to store 3 and gain up to +2 or +3 bomb stored or something.
The flash freeze/solar flare/thunderwave bombs would be cool, but would conflict with haze bombs enormously. One would just be better and the other would see no use. I think that's why there aren't any of what you're suggesting.
I think the pulse bomb would be excellent however, as would bringing back the old shard bombs. I miss the old shard bombs.
