I wouldn't say its 'easy' to miss stuff. There's no maps or minimaps so people legit just get turned around and miss things they normally wouldn't.I'm taking my time with this joint. Spent extra time sharpening up my parries...I'm still inconsistent but a LOT better after taking the advice @hex mentioned of paying attention to the sound along with visuals. The funny thing is I found the first boss to be the easiest enemy to parry so far.
For the vets of the game, I have a question. How easy is it to miss content? Like, I've seen one boss that's way too OP for my team this early on and I also met the creature that's got no legs and keeps asking for light. I pressed past both because I didn't find an item to light the torch and I don't have the parrying skills for a boss with one-hit kills and enough health to take me 20 turns to body. But I don't want to miss going back to those plot points, so I'm scared to move too far ahead (right now, I saw a message about Maelle being to the North, so I'm about to travel there).
Also, are there secret/hidden areas to find? This game feels like it's designed to have some hidden stuff, but I've only found some items off to the sides in crates and boxes. It's so early that I'm not surprised, but I don't want to keep wandering areas if I'm just wasting time and making myself confused.
People make a big deal about the missables because some of them are a big fukkin deal
You're also very, very early on in the game too so nothing you're dealing with is that significant
