Yes, the spammed 'try jumping,' 'hidden path ahead' japes are wearing quite thin. As are the juvenile "but hole" variations.
But, I have found some helpful messages. A couple directed me to catacombs or caves I would have otherwise missed, some have warned me of ambushes or enemies about to drop from above, and in the castle I read some helpful warnings of knights ahead and enemies waiting around corners. I always make sure to go back to upvote the helpful ones.
I have killed a couple of NPC invaders. Their AI is pretty good for the most part, but it is still just game AI and there are ways to cheese it. The ability to get two or three pebble casts off in rapid succession will generally mean that the AI will roll the first one like you would expect a human to, but they mostly don't roll the right way and so pop out of the roll into the second cast, with the small stagger usually enough to make them eat the third too. I haven't met one with a decent gap closing ability yet, so if I find melee a bit too tough with them, backstepping and casting is a solid strategy. Being able to switch up magic and melee as the situation demands has served me reasonably well so far.
I am so into this game! The world feels so big, with so much to discover and so many oddities and monstrositites. It all feels wonderfully mysterious and menacing. I am feeling a bit obsessed. I woke up this morning to find I had been having Elden Ring dreams...
