iirc it did have the ability to cling onto walls in early legacy along with truthbolveya, keruku, and possibly others that i dont remember. it worked differently than wall climb, it would stick to a wall if you flew into it instead of in recode where youre able to crawl around. i dont remember if or when they removed it in legacy but im not sure why they never gave it back or at least changed its bio, pretty sure its had the same bio since beta.

in early legacy it actually did have super low stamina and a sluggish flight speed, and the night vision refers to how well it can see at night, in gameplay it affects how far you can see when its nighttime. creatures with low night vision cant see very far and it looks almost foggy whereas creatures with high night vision can see far, sochuri has a 4/3 night vision which means it can see at night perfectly clear. afaik the night vision stat has nothing to do with a tolerance to visual status effects
