Flash bombs create some really interesting monster reactions that you'll want to understand (this knowledge becomes crucial in tougher hunts). When you toss either a flash pod or ez flash bomb, you'll see monsters react immediately with distinct behaviors, and knowing these tells you if you landed a good hit.

The most obvious sign is when they stagger or suddenly stop what they're doing - this happens because the intense light completely disrupts their sensory system. Flying monsters are particularly vulnerable here, since they'll actually crash down when blinded mid-flight (which creates a perfect opening for some heavy hits). You might notice some monsters clutching at their face or thrashing around wildly, and that's your cue to move in for damage.

Something interesting to keep in mind: while these guys don't have complex eye animations, each monster type has its own unique way of showing it's been blinded. You've got about 3-5 seconds of vulnerability to work with (try timing your bigger combos for these windows), and environmental lighting can affect how well your flash works. Watch for those telltale signs like head-shaking or erratic movements, because that's when you know you've got them right where you want them.

Tip: keep track of which monsters respond more dramatically to flashes - some are practically immune while others become completely helpless, and knowing the difference can really save your hunt.
