Long story short, since now getting a lvl 10 5* item is pretty hard I've been amassing a huge amount of 4* lvl 10 weapons ready to be upgraded, and now that I have enough radiants to upgrade one I'd like some opinions on which one I should upgrade.
Keep in mind that I'm not going for the absolute best and most useful in every situation but rather I'm going for "which of these would get the most benefit from an upgrade" and in minor part "from which weapon would I gain the most benefit"
The weapons are:
-Vile Striker
-Gigawatt Pulsar
-Radiant Sun Shards UV Fiend: Low
-Toxic Atomizer
-Fiery Atomizer
-Graviton Bomb (waiting on going for obsidian crusher so I won't upgrade to Vortex, still want some opinions in case we get an obsidian event soon)
Possible other candidates (not yet 4*/fully lvl'd):
-Crystal Bomb UV CTR:med
-Electron Charge UV CTR:low (also need to farm the krogmo coins for the recipe)
-Haze Bomb MK II (Same as above)
-Blackhawk
Thanks for your answers.
out of those, Electron Vortex (or Obsidian Crusher). Otherwise one of the haze bombs.
The swords and guns you listed, not so much.
Shard bombs are always going to be lame, unfortunately.
