"Brambles improves Thorns, Treant, and Entangling Roots damage by a flat percentage, and gives your Treants and attacks done to you while in Barkskin a chance to daze the target.".

"PvP Utility: Against a couple rogues or other duel-wielders with fast attack rates, this talent actually does decent damage over the course of the fight, but it's still pretty situational. The Treants also do a good amount more damage, and when coupled with a daze, its a very nice talent to have for PvP."

si me pegan en Barkskin si deja dazed jaja, el error es que los treants no dejan el dazed al golpear (ni cuando tengo barkskin activado, aunque se entiende que los treants no necesitan barkskin).
gracias.
