This can't be official, MVPs teleport in official if trapped and attacked, or if attacked and don't have clear sight to attacker.

This is determined by the mobs rude status skill. If an MVP is unable to reach the player, by walking then they will eventually use their " rude " skill, which just so happens to be teleport.

mob_skill_db.txt located in p(re)/folder

Examples:

1039,Baphomet@AL_TELEPORT,idle,26,1,10000,0,0,yes,self,rudeattacked,,,,,,,,1039,Baphomet@AL_TELEPORT,walk,26,1,5000,0,5000,yes,self,rudeattacked,,,,,,,,

You see that Baphomet like other MVPs will teleport away. So to prevent that from happening, just remove those 2 skills and they should stay there and get beat like the meanies they are D:

Thanks, but I m lazy to comment out  every mvp's 'rude attack' TELEPORT skills.

Is it possible adding  a  custom option on monster_ai ?

0x800: mvp mobs wont teleport away when they are trapped by an ice wall

 

and how about stop mvp's moving by an icewall part? how can I reproduce that behavior

That would be under mob.c for AI controls

My guess, is before it attempts to say it was rude attacked you need to add a check to see if the mvp is in an icewall.state ( do we use this? ). Sadly, I'm no where near able to do that with src code :/ but i'm pretty positive this is the bit that needs to be edited to do what you want. D:
