It should be able to but it won't knockback MVP and players in war of emperium.

Thats right. Last time MVPs can be knocked back and pushed away through the use of skills, but now all MVPs cannot be knocked back or pushed away. Skills like Charge arrow, Arrow Shower, Shield Charge, Spear Stab etc etc won't work on MVPs. They will do damage but no push back effect. Same goes to magic attacks like Jupitel Thunder and Firewall. The same effect also applies in WoE.

You will start as a High Novice with 100 stat points to distribute when you are at level 1.

Do whisper boss spawn on its own now? Usually when there are a lot of whisper boss at one area it means that ghostring is near.

Ghostring doesn't teleport like crazy actually. Its just that when its almost dying, it will teleport when you get near it making it really hard to kill with close range attacks.

At least thats what I think. Last time I try to sonic blow ghostring it will teleport when I get near it, especially when its almost dead. But when I use soul breaker it doesn't teleport at all.
