However, as far as my least favorite New Vegas creature goes, I can't decide between the frightening Spore Carriers and the incredibly annoying and overpowered Cazadors. The only way I have ever had a chance in killing these was when i glitched up a cliff wall that they somehow couldn't fly up, and took my time in killing off every single one of those darned bugs, one by one. They're very quick and very powerful, and damage with a crippling 70 attack damage, on top of having the Cazador Poison, which does -5 for 30 seconds.
Ridiculous.
