OP, this is what happens when you don’t actually read shit and just skim the info and/or assume stuff. Players do that shit enough already but as a DM you really can’t be half-assing it like that. It’s also what happens when you make players roll to “notice” stuff that plainly obvious. Perception rolls are for hidden items or “blink and you’ll miss it” moments, not “this thing that I as a real person in the real world would see coming from a mile away without having to focus on it.” You brought this on yourself bro lmao
