id take a stab and say the target wasnt flaged
any skill which doesnt do damage can not be used on players unless they are flagged, at war with you or on a siege field
Don't you have to force attack by holding ctrl ? even on a seige field? Invalid target comes up for me when i dont press ctrl to use erase or something (even to a warred clan), but for entangle i dont know
You can't entagle clan members, nor aliance members even if they are flaged, if your defending a castle you can neither entangle the other defending teams.
It only works on enemies under a siege, also outside area it only wors on non aliance members/party members and they need to be flaged.
Uhmmm i was attacking, and my target too, i even used force attack, and it did not work. Maybe if i use over an attacker when i am defending, or in open pvp, it will work. I have to try. Thanx
If im right, there is a ally created among the attackers and defenders during the siege, thats why you couldnt entangle another attacker. Try it next time on a defender :)
