The tells just aren't great for a lot of attacks. You just have to memorize the timing through trial and error for some stuff. It's another aspect to the parry mechanics that I'm not really a big fan of in a game like this. I think it's at odds with the RPG-ness of managing resources when you can potentially perfect block and negate all damage in most situations if you're technically proficient enough. One of the few changes from Remake that I'm not a big fan of. Though I see why people like it, as it greatly raises the skill ceiling.
Though if you aren't playing hard mode, blocking (especially with Steadfast Block materia) is plenty strong enough to get you through the game. No parrying needed!
Ah makes sense. Will give the steadfast block materia a shot as well (probably a better option for someone like me who's not great at timing parries to begin with). Not sure I've seen any for sale at this point of the game but will keep a look out. Thanks.
