Extended Thorns is a PvE Mesmer build that uses Dervish's ability to provide heavy amount of short-duration conditions on a foe with Extend Conditions and spread them with Epidemic while not going over the duration limit while maintaining your energy. This is designed to play with a balanced PvE party. This build was designed for the User:Defiant Elements/Contest.
