im level 42, idn what you guys are talking about, max tear gas bomb and you 1 shot mobs.
since level 32 ive been putting 1 mob gas down, and it will kill literally as many mobs as you can make run through it.
usually I just dash around and agro 20-40 mobs and drop 2-3 gas's everywhere and they all die.
it does 3500-4200 dmg now.
