Alright, thanks for the input, I was wondering since the weapon is quite difficult to acquire if you do not already have a large stash of crowns for it or pay money to get it from the box.
I'd vote as well but I do not fulfill the requirement for possessing 20 different bombs.
"Looking for someone to give their input on the Celestial Vortex, since it released just not long ago."
If you happen to care for my input, I'd say the bomb is in the same boat as Graviton Vortex. It is average-at-best because it is only notable for its usefulness as a Vortex bomb. Electron Vortex is a direct upgrade due to its Shock allowing stronger crowd control and giving you significantly more options after the bomb has been placed. Additionally, Obsidian Crusher is also a direct upgrade due to its nice Poison making it an anti-healer bomb on top of it already being a Vortex bomb; the poison effect also makes it safer to use because after enemies are randomly spread from the explosion, they will do reduced damage. Celestial Vortex is simply a Graviton Vortex but tacks on a tiny bit more damage after the explosion, and I believe it's generally thought that Vortex bombs are not used for their damage, but rather their extreme support. Strong Fire is quite interesting but actually does not add very much damage overall (considering how long it takes to charge a Vortex bomb) and in 99% of situations, both Electron Vortex and Obsidian Crusher are in all ways better than Celestial Vortex. I'm not sure if Celestial Vortex affects flying enemies; if it doesn't, then it is effectively useless against enemies such as Kats or Scarabs, but again, not sure about Celestial Vortex. Honestly, the only place I would see this bomb being more useful over both Electron Vortex and Obsidian Crusher is Dreams and Nightmares, but consistently charging Vortex bombs in that mission is basically suicide. I guess you could also use it to pick off weakened enemies to save like half a second-- I know personally I can not one-shot Zombies at Depth 25 with my Voltedge, they take one more hit to die; I guess tacking on that strong Fire would let them die on their own so I don't have to chase after them, but then again, I'd rather use Electron Vortex for that because it has the same effect and is a better choice overall. Because of all this, I'd personally give the bomb a 3, the same as I gave Graviton Vortex, and for the same reasons: "This is just one of those borderline bombs that are useful because its niche is so good, but the bomb itself isn't actually good when other options exist."
