so as of right now stealth is only really helpful for making some curios and hiding your pvp misdeeds, but how about we make stealth more.... stealthy.
Idea 1: Make it so stealth affects the aggro range of animals. Keep the aggro range they currently have for people with stealth 1 and make the aggro range decrease tiny amounts with every point. also give animals a perception score to weigh against your stealth score, such that its harder to sneak up on more powerful prey, but make it so that if you exceed an animal's perception score by enough you could potentially walk up to them and attack them without them running away or aggroing.... This would also give it an early game purpose so you could sneak up on birds and rabbits.
Idea 2: Make backstab a thing. Obviously PVPwise, humans have eyes and there will be no way to actually sneak up on someone, but as for the sneaking up on animals i suggested above, make it so that if you sneak up behind an animal you have the option to gain initiative points and make a single attack before combat begins (But definately make it impossible to do to players because then trolls will insta-gib AFK spruce's even easier.)
