HI currently the monsters doesn't behave like in real Tibia , I remember that iryont have already fix for it mind to commit ?;>
1.Dancestep - the creatures attempts to step randomly (1 second interval between checks) to any open square (north, south, east, or west) that keeps the monster within range of the target. If the square is blocked or occupied then the monster stays still until the next check. If there is a player on screen, but no target is reachable then the monster will no longer be restricted by range and can step anywhere (n,s,e,w) on screen. Monsters will only dancestep if they are within their desired range of the target or if no target is reachable.
there is dancestep but its for sure not 1sec.
its way more.
2/Running Away/Escaping - if a creature is below it's runonhealth value it will no longer attack the target with melee, it will however still use any of it's other abilities
it is wrong in otserv.
it attacks with melee.
3.There is also walkback feature.(would be good if configurable by config.lua)
4.distance monsters should slow down when they are reached by player
