Exactly what it says. Some tags are completely overpowering. Some tags seem useless. Some seem to make unavoidable conditions.
In fairness, tags seem to stack with themselves, so multiple STALK or FRIENDDIED tags will produce double, triple, etc the effect.
For instance:
-PLAYERCLOSE is very, very strong. wolves are playerclose. Adding that as an anger tag makes being close a near instant hostility. Even creatures with <-50 aggro will quickly get angsty with that as an anger tag. Similarly, putting it as a fear tag makes anything turn yellowbelly. Even zombies will run with little provocation.
-MEAT is a completely useless tag, it would seem. Ive had 10 of these as a placation tag and Ive noticed little in the way of discernable placations. Specifically on wolves. I had much better (and dynamic) results just removing the player close tag and doubling down on friendattacked and hurt.
-STALK is useful if used in quanities. the magic number to notice a real change of behavior is 4 to 5. with 4 to 5 stalk tags critters will maintain a tracking disposition and even run from a fire into the dark and continue tracking a player. Good for wolves, who will flee the fire and track you from the dark.
-FRIENDATTACKED AND FRIENDDIED seem relatively useless to. especially when other tags are much more effective at aggro changing.
-PLAYERWEAK is another pretty strong tag, although Im less sure exactly what it entails. It appears to be a relative tag; the monster compares stats? Either way, the critter appears to take into account friend/foe numbers and distance when deciding if the player is weak.
-FIRE. Fire is ungodly effective as a combat weapon, and solid fear/anger token.
-SOUND. Sound seems to be only moderately effective per ‘dose’, but since walking and combat all make noise it accumulates into something I think is unavoidable. Since sound only exists when something is bashed on, the player turns on/off/interacts with stuff, and when the player walks or fights, this seems like a hack to say 'when the player is around, you do [attack/neutralize/flee].
